Note: This may be related to Bug 356837 re: "cannot retrieve messages", but I don't have enough info on his experience to be sure. Thus a new report.
I repeatedly received the "RETR command did not succeed" message when trying to download one of my POP accounts. I have limited account creation/examination rights on that server and knew the password was good, the server was working and I had a few hundred KB of mail in the mailbox.
Trying to get a more specific error message, I opened Outlook Express and received error number 0x800420CD for two messages. (http://support.microsoft.com/kb/303194). The mail that followed the stuck messages popped down fine and I was left with 42 KB stuck on the server.
Rather than bother postmaster to delete the messages from my mailbox, I used Mailwasher to delete the 2 stuck spams.
Thunderbird was able to POP down after that.
Bottomline, Thunderbird shouldn't fail to retrieve all messages due to a problem with one message.
Reproducible: Didn't try
Steps to Reproduce:
(I have not tried to reproduce the error since I don't think our postmaster would want me to send the same message/same ID to the server repeatedly even if I could figure out how to do it.)
