I am not a postfix guy, but these two seem to have most of the info one 
would need.

Are you using postfix? You said something like, "using an email server 
like postfix", but if you are using sendmail or some other one, it is 
easier to google how to do smtp_auth for that server than it is to 
switch servers.
