This is typically a bad idea for another reason: With the amount of 
spam in circulation today, many - If not most - mail servers now flat 
out reject email that is not sent from reputable mail servers, where 
by reputable I mean a combination of:

   * Is not flagged as a spam relay
   * Doesn't live on a dynamic IP block
   * Has valid reverse pointer DNS configured
   * Pass SPF validation
   * et.c.

I think that the only safe approach is to use existing mail servers, 
either one that the user provides, or one that your company / 
organization can provide for the purpose of supporting your 
application. This still leaves the original question unanswered of 
course...

This is a very good "third party opportunity" for someone who would 
like to make a name for themselves in the Cocoa community - much like 
Sparkle, Growl, et.c.
