Hi I have been using evolution/cyrus/exim for 10 years - until yesterday! I upgraded to C6.7 and now there is no way I can find of connecting from evo to the cyrus imap(s) server [root at maui:~]$ ps -ef|grep imap cyrus 27768 1 0 15:21 ? 00:00:00 /usr/lib/cyrus-imapd/cyrus-master -d cyrus 27775 27768 0 15:21 ? 00:00:00 imapd -s cyrus 27779 27768 0 15:21 ? 00:00:00 imapd cyrus 27781 27768 0 15:21 ? 00:00:00 imapd cyrus 27782 27768 0 15:21 ? 00:00:00 imapd cyrus 27783 27768 0 15:21 ? 00:00:00 imapd cyrus 27933 27768 0 15:36 ? 00:00:00 imapd cyrus 28048 27768 0 15:46 ? 00:00:00 imapd evo is running on a fully updated F22 machine, cyrus/exim on C6.7 k-9 mail on a tablet and a mobile no longer connect even tried thunderbird which also would not connect When trying to connect with evo I get Failed to open folder The reported error was "Could not connect to 148.197.29.5: Connection refused" If I try to change things by editing the "Recieving Email" menu ie by changing the "Encryption method" from "SSL on a dedicated port" 993 to "No encryption" it still fails In fact just hitting Authentication "Check for supported types" gives Failed to query server for a list of supported authentication mechanisms.

So, mucking with your clients' encryption/authentication settings probably won't do anything. You might also want to use netstat to confirm what's listening as your imapd and to confirm that it's listening on the external interface (not just localhost). Something like: netstat -pln | egrep ':993|:143' as root, should get the interesting bits. Also, you might want to check to see if the cyrus config files were touched with the update (look also for rpmnew and rpmold cyrus config files).
