Here's a poser.
I compose a message, or hit reply. Hit "send."
Wait. The grey box appears up top, there's indication that something's happening...then I'm back at the main page, and there's no indication my message actually got sent. No green box, no "replied" icon, and...well, nobody receiving it on the other end. My message is now gone, off into the ether, never to be seen again.
Obviously this makes my email client not especially useful.
No errors in the error log, no entry in the sendmail log for the message. It's just gone. And it's happening to me about 1 out of every two messages. Maillog is less-than-enlightening too. Just a lot of imap init/login/logout messages.
Ideas?
