Sendmail on OSX through Rev

[Richard Miller]

We are using a dedicated Mac Mini as a server through an ISP. We've  
asked them for a way to send emails from the Mini so we can avoid  
using SMTP relay. This is the response they sent back. I'm hoping  
someone here can tell us how to implement this through Rev.

"To generate emails from the Mini, you just need to call /usr/sbin/ 
sendmail or /usr/sbin/postfix withthe appropriate arguments.  Turning  
on postfix as an SMTP server will only affect the Mini's ability to  
receive email.

If you use '/usr/sbin/sendmail -t -oi' as the command, then you can  
feed it the appropriate headers (see below) and it will work."
