I've recently had a small issue w/ T-Bird on my wife's XP laptop since I've moved to Dovecot...the logs indicated she had a new msg., she thought she heard a "ding" indicating a new msg., but there was no indication of it in T-Bird, and clicking "Get Mail" didn't do anything. I hit the "offline" icon at the bottom corner, put it back online, and hit "Get Messages," and all was fine. So...problem w/ T-Bird or Dovecot, jury is out, but I have not seen any common occurrences of this issue, so nothing I'm all that worried about.
There are two ways to fix this.
Thunderbird will let you set per-folder to check for new messages.
Right click the folder, select Properties, and tick "Check this folder for new messages".
