Created attachment 329087 [details] mail log showing cyrus errors Nothing works after upgrading to cyrus-imapd-2.3.13-1.fc11.i386. /var/log/maillog attached.
Downgrading to cyrus-imapd-2.3.12p2-3.fc10.i386 makes the problem go away.
This is the same problem as bug 479693. I guess it doesn't like the newest build tools.
fixed (I hope there is no other problem) and building 2.3.13-2
cyrus-imapd-2.3.13-3.fc10 has been pushed to the Fedora 10 stable repository. If problems still persist, please make note of it in this bug report.
