I take it back. In my case, the problem was due to courier-imap being configured to only watch INBOX for changes. This setting:
IMAP_CHECK_ALL_FOLDERS=1 in /etc/courier/imapd fixes this. So in many cases, this problem may not be related to thunderbird, but to the IMAP server being thrifty. -- New mail is not noticed in IMAP subfolders https://bugs.launchpad.net/bugs/106730 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
