I've read various documents on mail servers and Netapps and other NFS servers etc, . but thought I would ask the question.
What MTA (sendmail, postfix, qmail, exim, etc.) have admins chosen to run and their reasoning if they would be open to sharing their feelings.
Errol on Wietses archives there is lots discussion on its use with Netapp. There is some major flames on super tuning for high speed relaying to achieve 300 messages relayed per second.
We don't use postfix on netapp but even on an intel box (IDE) it can handle some monster loads on relaying, rejecting unknown users etc.. We normally have about 1000 emails stuck in the queue for unknown destinations and it does not choke like Sendmail would...
The configuration of postfix as very easily understood.
One thing that Exim does is have some mad macro language to be able to put data into databases and be able to build your own smart logic into it Eg... Record in mysql the IP of any server that sends me email to unknown users, every time email delivery is attempted check the IP in the mysql if it has sent me more than x unknown users in the past hour reject the message... etc...
if you just need a good powerful email, steady, easy to manage. Postfix would be my choice.
