Both of us run watchdog scripts (I run clmilter_watch every 15 minutes) so, at worst, clamav-milter will be down for 15 minutes. In your case, all mail delivery will stop, and I think outgoing mail will also be broken. So, not only will your mailserver be down, but your users won't be able to contact you to let you know it's down. Of course, a 15-minute downtime might be acceptable to you.
Use a startup script like this (crude) example and you wait only a few seconds:
#! /bin/sh # Start daemon, restart if it dies, send notification to syslog
start_clamav_milter () { /usr/bin/clamav_milter [args] }
# main While :; do start_clamav_milter sleep 5 logger -t clamav -p local5.crit "Damn milter quit again" done
That only saves you if clamav-milter crashes, not if it hangs, or if the virus database gets borked, or any number of other problems. To guard against all possible failures you need clmilter_watch, available at
