*** Bug 222831 has been marked as a duplicate of this bug. ***

Same issue as described - also causes problems with saving to Sent Items folder after sending a message - with same error message.

I can verify that this is a bug. It drives me crazy -- I'm sending via SMTP but pulling/saving via IMAP -- so my compositions send okay but fail when attempting to save to the Sent folder. Then I have to explicitly save to Drafts. By the end of the day I usually have a dozen or so in the Drafts folder that I have to manually move into the Sent folder. This is the single most aggravating behavioral aspect of mozilla for me at the moment. Perhaps a small bug, but a huge irriation that impacts usability. I see that this bug is marked for Thunderbird, but I'm experiencing it with version 1.6 of MailNews in the regular mozilla distro. I see two possible solutions -- a) increasing the timeout or b) repeating the attempt after failure. When I encounter it, I usually have no problems immediately afterwards if I try again. Thanks for all the good work. Cheers, Matt

we need an imap log from someone who sees this. http://www.mozilla.org/quality/mailnews/mail-troubleshoot.html#imap

Can Thunderbird generate an IMAP log as well? The instructions in the link above do not seem to work. We are experiencing some reports of Thunderbird failing to notice new messages on the server and I suspect IMAP autologout behavior.

yes the same instructions apply for seamonkey and thunderbird

I'm also seeing this in TB 0.7.1. When I still was using a netgear mr814 router I saw the same thing as the person comment #3. Now with a linksys router it's a bit better but a folder sometimes just doesn't open. I have to quit thunderbird and then restart it again.

if more information or a patch becomes available renominate. --thanks

This is the IMAP conversation of me opening Thunderbird and sending a message. I waited for some time for "Copy to Sent Folder" to complete. When it didn't, I cancelled and tried to save to Drafts. That never completed either. I'm using the latest version of Courier IMAP and Thunderbird 0.9. (Although, I've seen the same behavior under the new RC1)

Still seeing this with 1.0

this is already a new feature that is in the 1.1 test builds. Tools / options / adanced / Connection timeout field
