User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b3) Gecko/20050708 Firefox/1.0+ Build Identifier: version 1.0+ (20050708) Windows sometimes opens multiple login dialogs, sometimes the dialogs have to be cancelled one by one, often asks for login again even though the previous login was successful. Reproducible: Always Steps to Reproduce: 1. configure Thunderbird to talk to an IMAP server via IMAP proxy (for example SpamPal); set a minimal update interval (1 minute?); 2. open a folder 3. make server inaccessible (disconnect the cord); 4. login failed dialog should appear; 5. try to login,it should fail; 6. wait a little; 7. connect the cord back; 8. login again Actual Results: you will be prompted again to login Expected Results: the last result should be final - if either if Cancel is pressed or the last login was successful - no more login requests should be open. It looks like Thunderbird wants to separately report an error and ask to login for every connection it makes, but sometimes I have to cancel more then 5 login dialogs.

maybe, this is dup of bug 219162. *** This bug has been marked as a duplicate of 219162 ***

Bug 219162 has been fixed in Mozilla 1.5 final. So this is (dup of) another bug?

*** This bug has been marked as a duplicate of 160425 ***

I just got my account locked out because Thinderbird tried to login 5 times in a row with my old password. As if once failed login is not enough.

This maybe a duplicate of bug 249240 .

?!?! I just got my account locked out again, because Thunderbird decided to try to login with my old password 4 times in a row. When is it going to be fixed. Corporate users usually have password renewal policy. It is a nightmare every time the password should be changed.

Hope the following helps: 1. please always supply your release of software from help|about 2. do any of these open bugs match your issue http://tinyurl.com/rfhqa 3. when you comment next, an imap protocol log will be helpful - instructions here and put "imap" in for <protocol> http://www.mozilla.org/quality/mailnews/mail-troubleshoot.html#imap - upload (attach) the log as a FILE to this bug

Alexey, could you please check the issue still occurs in the latest supported Thunderbird 2.0.0.x or trunk nightlies?
