That was an issue I had to work through.. First, we use
http://www.authsmtp.com/ to send mail for us. This is actually a really
awesome service for sending mail. Postfix has been reconfigured to relay
mail (see
http://pauldowman.com/2008/02/17/smtp-mail-from-ec2-web-server-setup/).

The real trick was making nagios' notification scripts work with postfix to
set a reasonable sender. On CentOS systems, if you use /usr/bin/Mail, it
uses Sendmail and you can't really set an envelop sender. Your emails come
from nag...@$hostname. This is bad for Authsmtp.

I ultimately replaced /usr/bin/Mail with a shell script that used
sendmail.postfix to queue the outgoing message. Postfix then set the correct
sender info.
