I’m frustrated

Can't send email to comcast.net customers

My company has comcast business broadband service, which is probably not related to the problem here: We host our own email. When we send email to recipients on comcast.net, it comes back as delayed or undeliverable. Comcast tech support tells me our IP is not on Comcast's "block list." I have been unable to determine why we cannot send email to comcast.net accounts. I'm reluctant to call Comcast tech support again, because the technicians who answer often know less than I do -- some don't even know what a static IP is, and others have insisted that the static IP config on our modem needs to be reconfigured (it doesn't) and when they attempt to re-build the file, we always lose all email service for hours, until I call repeatedly to have someone else repeat the process, correctly. Any help will be welcome.

    Our email to subscribers on the comcast.net domain was being blocked because our email server IP address was on Comcast's "block" list. All email from that IP was being rejected. This has happened to us with a handful of other ISPs, and we were well aware that this was a likely cause. However, I had called Comcast technical support more than once about the problem and the technicians there had reported back that they checked the "block list" and our IP was not on it. Only when I posted on getsatisfaction.com did I attract the attention of a Comcast official who was able to tell me that Comcast Technical Support is not competent to check the block list. He referred me to Comcast's Customer Security Assurance department, which deals with security, spam, and the block list. At that point, the problem became clear, and they removed us from the list. As you may know, there are many ways to get on the list. Being a spammer is one, but we're not spamming; we don't even send out legitimate mass mailings. It may have happened because there was a reverse-DNS lookup issue on some DNS servers. We had already corrected that issue at the time we began having difficulties with Comcast. In any case, the problem appears to be solved. Lesson: You can't take Comcast Technical Support at their word. Keep pushing in every way you can.

    If your IP address is causing mail to be blocked, please review the return mail message and go to the following website

    http://security.comcast.net/get-help/...

    The return message will have an error code, and the web link above will provide you the FAQ for the specific error code. Once you access the FAQ it will explain how to correct this. We certainly do not want to cause any inconvenience, but these measures are designed to prevent spam. If you are using a shared server, others may have used it for spam causing the trouble.

    Caffeineking,
    First I thought I was the king of caffeine! If you did not receive a returned email, your original probably landed in her junkmail filer. If you did receive a return message, I would need to see that to understand.

    Thank you everyone!

  • I am having a similar issue, I am not on the rbl, but I did have an issue last week with an infected pc. Nothing has changed on my side since then. When I try to send to comcast.net it times out. The mail just sits in my queue. The only thing left for me to try and change is the ptr record for our ip address. It resolves to a different name then our mail servers name. But again it has always been this way. Everything checks out fine when i go to mxtoolbox.com

  • As I said before go to www.comcastsupport.com/rbl and fill out the form. We were not on any blacklist, our IP was fine at mxtoolbox.com but we could not send to Comcast email addresses. Once I submitted this form I received an email from Comcast saying we were removed from their blocklist and we could then send email fine to Comcast emails.

  • Here is what I found out. There is more to it then the RBL list. I have two outgoing connections from our Office. Comcast seemed to take notice to our server after we had the virus a day or two before we could not send to comcast. If you are not on the RBL list you need to call their second level security team to have access again to their servers. They will ask you what happened and what steps you took to correct it. Their office is only open from like 9-12 two days a week I think so good luck. They were able to correct all my issues dealing with comcast.

    My first problem was I had to creat RDNS records for both of my outgoing interfaces, that resolved correctly back to my server. If your RDNS record is just a standard given by lets say XO like 111-111-111-111-ipaddress-server-xo You need it resolve correctly to your server.

    My advice would be to call comcast, and see if you can speak to the security team,

    Good luck.

  • We have this situation too. The problem is, no email is returned, hence the solution provided by the Comcast Cares technician to check the error code doesn't solve the problem.

    The symptom is many of our parents call and complain that we are not communicating by email. These parents are Comcast customers - we have hundreds who use Comcast and cannot communicate by email.

    - Matt Mello, Director of Technology, Holly Area Schools
    • Meant to say that we also received an email back from Comcast indicating our MX server's IP address was not blocked. Comcast needs to be more forthcoming as to what needs to be in place for mail engines to properly communicate with theirs. This problem did not exist as of last November, when we were able to communicate with our parents who have Comcast email accounts.

Its costs me too much money to work with them. I wish that Comcast would have used some sense in this decision to block IP addresses, as they are the only organization that I can not communicate with

  • Step one.

    Go to mxtoolbox.com and see if you are blacklisted anywhere.
    If you are fix the problem, open relay, or sending spam etc. Then get removed from the blacklist

    Step two

    Check and make sure your mx records and rdns records are correct.

    Step three

    Check the rbl list mentioned above from comcast.

    Step four
    http://security.comcast.net/get-help/...
    Contact comcast security to have them check out their mail server response.

    Once you are on a black list or on an rbl filter it is hard to get back off of it sometimes. We had an issue with att.com and comcast.com at one time. Most big corporations use a rbl list anymore, I use spamhaus to reject anyone that is on their blacklist.

    mxtoolbox.com will tell you if your mail server is behaving the way it should.

  • I’m frustrated
    We are having the SAME issue.. but we are NOT getting any bounced emails or message that the email was Undeliverable which is quite frustrating. The only reason we knew it was occuring is because our own co-workers weren't getting their work tasks on their email from home... my assistants have called comcast & opened ticket.. several days later no resolution. This morning i received 2 calls from clients indicating they didn't receive a TIME SENSITVE document i sent them last week!! Very frustrating!!! I have a couple of other employees with home comcast emails that receive them just fine.. and yet 2 others including several other clients aren't getting my emails. and i get NO indication they didn't get the emails... so it's coin toss as to whether my mail ever gets to them. I don't have the time or the patience to contact each & every person i email to ASK them if they recieved my email... defeats the purpose!!!!!!!!!!!!

    This is an example of Comcast picking and choosing what standards they want to enforce. We operate a site that is a no-profit discssion board. We don't receive any mail so we don't have an MX record. So no mail to Comcast customers and they are the ones who lose out. We recommend they find another ISP.

    I cant tell you how many times I have filled out Comcast forms to be removed from their list, but I keep hearing "You are not on our naughty list". I am going to have to post a message on my site that comcast customers might as well not sign up. I have not had any problems with any other ISP.

  • I have a similar prob to most people here. I use Comcast only as my ISP, am on a mac, & have a mac.com email address. Since a few wks ago (that I know of), any email I send to anyone w/a comcast.net email address does not rec'v it. Even if THEY email ME first & I hit the REPLY button. Doesn't bounce back to me, nor does it go in their spam folder, it just disappears. 2 separate 1 hr ph calls w/7 diff comcast people who keep transferring me to the wrong person or to another round of endless voice menu options, ended w/the last comcast 'tech supp' person who didn't know what she was talking about. Insisted it was a Mac Mail problem even tho the ONLY common denominator is: ONLY comcast customers not rec'ving my emails, & ONLY from 1 of my mac.com addresses (sending from the other gets thru). She insists I cannot possibly be flagged as spam (as I insist) & that any central place that can block or unblock anyone not using a comcast address doesn't exist & that it's not possible for comcast to block a non-comcast email address. WRONG. By that logic, any 'buy Viagra, click here' etc. spam would never get blocked because they're not a comcast address. Finding out little by little that my emails were never rec'd to some people has cost my business hundreds of $ in lost sales... Can anyone help?

  • Hi Kathie. I feel for you, as I went through this for weeks with Comcast, and didn't even know it was happening for about a month. (I thought people just didn't like me anymore!) But anyway, just a thought, and not to let Comcast off the hook here...but I went back and forth for weeks with Dell, Microsoft and Comcast. Each blaming the other. The problem was finally resolved when Microsoft gave me Office 2007 to replace the Windows Mail that came with my windows Vista on my new computer. Now I don't know if Comcast was to blame for mail coming from Windows Mail, or if it was a bug in Windows mail, but that was what fixed my issue. Now I know you said you're on a Mac, so I'm assuming that's not Windows!..but thought I should tell you how mine was resolved.

    But having said that, Comcast was no help for weeks. The frontline techs are useless. They "escalate" the problem to techs that you can't speak to who'll call you back in "24 to 48 hours". (so if you're not home for the next 48 hours straight you're likely to miss this call.) And all they do is go into your e-mail without permission, change your passcode and send an e-mail from your box to your own box. If it goes through you are deemed crazy and they tell you everything is fine. Which of course it's not because most e-mails don't make it through. Try contacting corporate headquarters in Philadelphia. Office of the President. This link will give you the details. THEY are actually very helpful there and will call you back. I forget the receptionists name but she's very nice and helpful. http://wiki.answers.com/Q/What_is_the...

  • Thx for the reply yankeestonk! :-) Yes, you're right, Windows isn't my issue since I use Mac Mail for my Mac. You're also right about the frontline techs... I am absolutely sure it is NOT my mail program (despite their saying it is) & that I simply need the higher eschelon to unblock me... Mac tech supp guy was extremely patient, knowledgeable & spent time w/other techs, agreeing that it is definitely a comcast issue. (they were not passing the buck). In fact, the Mac guy Googled the problem & found this site for me, proving that since many other people (& non-MacMail users) have had the same issue, it is Comcast... Luckily, right after I posted this, I emailed a comcast person I found here, & got a quick reply from someone at the Comcast corp office who said he'll research it w/his team & asked for my contact ph#. Hopefully this will resolve it; if not, i'll try your link. Thx for your help! :-)

  • Sorry u're having probs too George... After 4 frustrating hrs Sun & Mon, w/ 7 comcast tech supp's (lower level r useless & don't even make common sense), a nice upper level tech emailed me from this site on Tues, having me do multiple test emails to various addresses, then sent me to another tech guy. This last guy finally ended w/some long-winded jibberish-sounding (poor, confusing grammar like he was a foreigner) conclusion about it being a random thing from a 3rd party server that C'cast uses that blocked anyone w/a mac.com address because at some point someone else w/a mac address sent spam to a c'cast customer... Simultaneously, the prev guy emailed me saying another long-winded thing about mac's servers, bad IP addresses, etc. Btw, the Apple tech I called next (whom I trust) said they never heard of anything like that, & most likely someone at C'cast realized after all my complaining that they WERE blocking me as spam, but shouldn't, so they simply unblocked me. Esp since, magically during all this, 2 of my c'cast friends who weren't getting my emails, now suddenly did.. However, a few minutes ago, I got 2 more emails from a business person I haven't met (& have no ph# for) who's been trying to reach me & hasn't rec'd my Replies to her. I'm hoping she gets this next one I'll send because if not, then my prob really isn't resolved after all..

    Click on the link on top, the we_can_help_@cable.comcast.com like I did & see what they say. I'm very curious as to what they tell you. Would you post me back here & let me know what happens? good luck! :-)

  • Since I resolved my issue with comcast and various other domains through the years I will see if I can help.

    We run our own internal email server so I am able to track the transactions to and from other mail servers.

    If you can't send emails to comcast you are most likely blocked comcast and other ISP's as well. In order to help prevent spamming and the spread of viruses if an IP address or mail server is sending out spam the ISP will block that IP or mail server until they are absolutely sure that the address is not sending spam.

    If you are getting a message refused error or just a general message failed you are blocked by that domain.

    Most ISP's require your mail server to have a properly formed dns entry's. They also like your server to have a static IP.

    If you have one machine on your network that is infected with a virus and sending out spam they WILL block your domain from sending out mail.

    go to http://security.comcast.net/get-help/... to see what they say.

    go to http://mxtoolbox.com/ to check out your mail server and see how its working

    If your mail is not going through it is most likely your fault.

  • I’m frustrated
    Mike from Comcast helped me with my problem. Same issue: could not sent to Comcast.net. Found out our e-mail was marked as SPAM by someone and so they blocked all e-mail from us.
    Two things I had to do. They told me to change my "disclaimer" on the bottom of my e-mails. I did that and it was fine. They told me to set up the SPAM folder where it just does not delete spam but acutally puts them in a folder. That was not set automatically.

    Third, they called the SPAM crew and they cleared our domain.

    Someone sent a large amount of personal mail out and people marked it as SPAM.
    Thanks.

  • thx Daniel for the reply. What did u change your disclaimer from & to? At the bottom of my email flyers mine says: " I love staying in touch with my friends/customers & hope you enjoy my communications too! But if you'd like to unsubscribe from future mailings, please let me know, at: proudpeacock@mac.com" What should I change it to?

    SInce I do not have a 'comcast.net' email address myself (i am a 'mac.com'), how could I set up a SPAM folder to put my email into other people's SPAM folders?

    After all this mess w/the tech support people, 2 of my friends on comcast.net started rec'ving my emails again, which leads me to believe (hope) that they unblocked me. However, since I NEVER got any of them bounced back, I had no idea mine were not getting thru until I realized it from my friend. I'm assuming that since my emails r now getting thru to my friend, that they're also getting thru to my customers, but I really have no way to know for sure.

    In addition, my emails WERE being bounced back to me from charter.net customers, saying that my emails were SPAM. They have a link to where u can email them to request being unblocked. (No phone#). I emailed them twice & never got any response one way or the other...

  • If you're being blocked by Comcast, mail stuck in the queue, and not getting a response message, except from your mail server that your message has been delayed (Exchange 2003), then you can get that error message another way.

    From a cmd prompt: telnet mx1.comcast.net 25
    This is what you'll see (similar)

    554 imta01.westchester.pa.mail.comcast.net comcast xxx.xxx.xxx.xxx Comcast block for spam. Please see http://help.comcast.net/content/faq/B...

    Connection to host lost.

    xxx.xxx.xxx.xxx will be the public IP address of your mail server.
    This is the message I got today from one of my customer's mail servers when trying to make a direct connection to one of Comcast's mail servers.

    You then must click on the link on this page to request to have the block removed.

    I host my own email and I am also a comcast customer. I am not able to send to comcast.net sometimes. This seems to affect certain accounts and not all the time. I am receiving a 554 error (invalid ptr record) I have changed it to show the correct ptr and it'll work for more comcast.net accounts. But not all. Sometimes when it denies an email, if we resend it, it will go through.

    I took my company name out of my disclaimer to fix. Maybe it is @mac.com or just an e-mail in the disclaimer. I actually removed mine and had Comcast reset my account on their end.

  • Our ISP is Comcast but we use our own mail server. We can send email to any Yahoo email address just fine but the Yahoo user cannot get a reply to us. They do not get an undeliverable notice. From the Yahoo user's viewpoint, it appears to go through just fine. On the receiver side, nothing comes through. Gmail accounts work just fine as do other domains, just not Yahoo.

    Any ideas on what I should do?

    Since Comcast is obviously at fault here (because they have more rejects than other providers), THEY SHOULD FIX IT.
    Either analyze all the areas in their programs and fix them
    or
    Create a single dept, to investigate our problems.
    Let that dept rummage around in all the places (and depts) where problems can occur, and fix each complaint.
    WE SHOULD NOT HAVE TO SUFFER BEING SENT FROM DEPT TO DEPT, TO NARROW DOWN WHICH OF THEIR PROGRAMS IS STUFFING UP.

    MY COMCAST.NET BLACKLIST REMOVAL INSTRUCTIONS:
    Just because they say you are not blocked doesn't mean you aren't.
    Open command prompt and type: telnet mx1.comcast.net 25
    Comcast.net should reply with an error of why it’s rejecting email.
    Research the error code and find out which blacklist you’re on.
    Comcast.net subscribes to the following blacklist services:
    Sendersource.org
    SpamHaus
    TrendMicro
    CloudMark
    Comcast Internal RBL
    Request removal from the correct blacklist
    Call Comcast Customer Security Assurance Department:
    888-565-4329 ext. 3,1,1
    Believe it or not they will eventually answer and probably help out.
    They can whitelist you temporarily while you are removed from the other RBLs.

  • Rob,
    Try the telnet command from a different computer. Also, if your using Windows 7 you'll need to download a telnet utility such as Putty.exe

    Same is happening to me. All of a sudden a few months ago all all of the emails that I send to friends with comcast.net email address bounce back to me saying that the server is taking too long to respond. Why should any of us who aren't even with Comcast have to deal this this AT ALL???

    A company this big ought to be able to fix this problem.

  • Hello I am hoping you can help me. We are not on any blacklist and comcast just sent us an email that we are not on their blacklist however non of our comcast.net customers can receive emails from us. No bounce back emails come to us - and they all check their spam folders. Its like our emails just die in space when we hit send. I really hate having to tell our customers to get a gmail or yahoo account just to do business with us.
    • I'm having the exact same problem as you. I discovered a couple of days ago it is because I use my nonprofit's website url in my email signature. I removed the signature, and all mail goes through. But not really. Any email that I send that has the url (the url that was in my signature) in it in any form does not make it to the recipient.
      I gave Comcast my domain name ip address, and their email response said that I am not on their block list. So looks like I'm at a dead end.
      I will try calling tomorrow (again) but this time will call the number that Jeff gave:
      1.888.565.4329
      Comcast Security Assurance Department

      Good luck to us all!

  • I haven't tried this yet, but read the answer here:

    Specifically Gabe M's response, which says:

    I WILL SAVE EVERYONE A TON OF TIME........................IF YOU EVER HAVE THIS PROBLEM CALL:

    1.888.565.4329
    Comcast Security Assurance Department

    **It took me 5 hours to get to this point, when I finally got this phone number and called they knew exactly what the problem was and how to fix it. They took care of it immediately.

    Don't listen to any of the people at comcast, just call the security department, they are life savers!

    I feel so relieved, finally!!! Thanks for the help.

  • I will try some of the recommendations here, but the recommendation that makes the most sense to me is to ditch Comcast. I NEVER had this problem with any other service provider, and Comcast seems to have no respect for the impact of blocked emails.
