I installed FC5 (clean install) on Saturday and have finally gotten around to looking at the logs. I'm seeing two different messages related to Cyrus IMAP, the first in the LogWatch daily report: --------------------- sasl auth daemon Begin ------------------------ **Unmatched Entries** Deprecated pam_stack module called from service "imap" Deprecated pam_stack module called from service "imap" The second in /var/log/messages: imap[14490]: auxpropfunc error invalid parameter supplied imaps[14493]: auxpropfunc error invalid parameter supplied lmtpunix[14506]: auxpropfunc error invalid parameter supplied Below are my cyrus.conf and imapd.conf files. These files were taken from the FC4 installation along with the /var/spool/imap and /var/lib/imap directories. Any hints.
