I believe there is no "syslog_facility:" option in cyrus 2.4 (at least I
was unable to find it). You can configure it in cyrus3 and maybe in
cyrus 2.5.

So in /etc/imapd.conf I would remove the syslog_facility line and set:
syslog_prefix: cyrus

And in /etc/rsyslog.conf:
mail.*       -/var/log/maillog

Restart rsyslog and check logs for cyrus/something ...
