In general postfix seems to be faster than sendmail in my testing and
experience for MTA duties. Specific to mailscanner and the hold queue
for postfix vs. running 2 instances for sendmail it may be a wash, but
for outbound delivery of scanned mails it seems to work best for me. If I
have queue backlogs it seems to handle that better than sendmail too. But
honestly performance is a minor consideration. Config flexibility, debug
capability, I liked better in postfix.
I ran mailscanner+sendmail for 3 yrs or so (redhat), and switched to
amavsid +postfix for 3 yrs or so (debian), found that leaner and faster.
Switched back to mailscanner+postfix (debian) and like that the best
of all the setups.
My current setup is 5 clustered postfix based scanners in diverse
datacenters. MySQL backend for config management, web admin
tools, quarantine centralization, etc. Each box though can run
independently so if the link to the mysql cluster is down, or if mysql
cluster is down, they keep on processing email.
