Today I tried this again with the same non-synchronizing e-mails with 'Dovecot' instead of 'Courier' as the IMAP-server in TB 17.0.6
All the previous blocking mails stored in a non-synchronizing folder downloaded right away when I clicked on that folder, and all have got a green gloda spot now. Thunderbird has even ended downloading all other mail. So there probably is a difference between the Dovecot and Courier- mailservers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1074260 Title: Thunderbird heavy IMAP traffic downloading messages To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/1074260/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
