Hi, I have a fedora30 desktop with Thunderbird 68.1.1 (64-bit), although I'm not sure the version matters. It's configured to connect using IMAP to a dovecot system also on fedora30. The problem is that when Thunderbird is open on multiple computers (the other is my Windows laptop), virtually every message received is duplicated. I'm not entirely surprised, considering two systems are competing for the same connection. However, this doesn't happen with my K-9 client on my phone with Thunderbird also open on my desktop. Perhaps someone knows of a Thunderbird or dovecot setting that maybe closes the connection when it's done updating, or some other configuration option that prevents this? _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
