I've discovered -- and fixed -- situations where a Thunderbird 3 email account can receive mail, but cannot send. Even though all the settings for both incoming (POP) and outgoing (smtp) are correct. Despite deleting the account and rebuilding it.
Nothing seems to work. Even when everything is set correctly and there appears to be no "sane reason" why it is not sending. I feel there's a glitch in Thunderbird 3 concerning the password management. Or the lack of it.
But there's an easy fix.
I've noted that when I have changed passwords for various email accounts from my ISP, Thunderbird 3 failed to "update" the outgoing password. Does that sound similar?
Now try the flawed email account using Sea Monkey 2.0.1. It works, doesn't it? But if it errs there too, take a look at the following
See what Sea Monkey has that Thunderbird doesn't. A "Password Manager" utility.
>"View Saved Passwords." "View Passwords." Sort by account name.
Take a look. The erroring accounts probably have conflicting passwords for the outgoing settings. At least mine did. In Sea Monkey, simply delete all passwords associated with the erroring accounts. It will leave your settings intact. Now restart Sea Monkey.
You'll get a prompt to enter the deleted password for the account. Now open "Password Manager" and look. The info has been rebuilt and both the incoming and outgoing passwords match.
Now try the account out. You should get and send email fine now. And a lot faster, too, I note.
For some reason, Thunderbird 3 holds older, outdated passwords per account email address. To fix your outgoing email problem on Thunderbird 3, install the following add-on:
Password Exporter 1.2

And once installed, go to Options with this add-on and follow the above steps for deleting the phantom passwords. Restart Thunderbird 3.
You'll get a prompt to enter the deleted password for the account. Now open "Password Manager" and look. The info has been rebuilt and both the incoming and outgoing passwords should match. Now try the account out. You should get and send email fine now. And a lot faster, too, I note.
It may not solve various "receive but cannot send email in Thunderbird 3" issues, but it solved mine.
