+1. Let me throw in something else. If youa re sending more than one email 
at a time (to more than one person simultaneously), Postfix will beat 
Sendmail. It can handle high loads better than Sendmail as well. Is it the 
fastest MTA out there? Doing some Google Fu some time ago, it's right 
there with the very fastest ones. For my job, I need to send out emergency 
notifications to 400 people at once. With Sendmail, that took over 7 
minutes. With Postfix, that takes seconds, and mostly because of the 
"handshaking" with the downstream host. If it's fast, I haven't even got 
time to send the message, get to a command prompt and type "mailq" and see 
it leaving the outbox queue...because it is already gone!
