using

|
|  I was able to push just under 1200 messages per minute (1.7 million per
| day) using MS 4.35.11 and Postfix 2.1.5, SA 3, DCC, Razor and RBLS. For my
| tests I made the following changes to the system:
|
|  Caching nameserver
|  Ran nscd
|  Set /var/spool/MailScanner as tmpfs
|  Disabled atime record keeping on /var/log
|  Disabled syslog synching in /etc/syslog.conf
|
|
|  I only had a chance to test Sendmail and Postfix at the time. I'll
try out
| Exim at another date. However, I couldn't get Sendmail to run anywhere
near
| the performance levels I saw with postfix. I could only get Sendmail
to run
| with 400 messages per minute with the system configured identically.
|
|  Even without MailScanner, Sendmail performed extremely poorly. As a pure
| relay server, Postfix was able to handle close to 2400 messages per minute
| (almost 3.5 million per day). Sendmail could only make it up to 900
messages
| per minute.

Funny. I always see it the other way around. Postfix performs
:extremely: poor and sendmail very, very well. The best along with Exim.
I will leave zMailer out of the equation here. Would you mind sending me
your sendmail.mc off list ? Thanks
