We just set up a new IP address for our mail system and installed Postfix instead of Sendmail as the MTA.
Everything else is exactly the same… same server hardware, same old arpReach email system.
With Sendmail we were sending 10,000 emails per hour.
With Postfix we are now sending 80,000 emails per hour.
Just thought you might like to know Postfix is waaaaaaay faster than Sendmail.
I'm trying to use postfix as my MTA as well. Hoping for some extra speed.
How did you get it working from arpreach? When I try to set up a new email system, i only get two options, SMTP & Sendmail.
Thanks for sharing this. Really good to know.
