I appreciate Graham's suggestion, but after having a good look-see at 
Postfix last night, I'm leaning toward giving it a shot.  It 
certainly comes well-recommended.  However, it might be wise to 
investigate Exim as well.  Any thoughts as to relative strengths and 
weaknesses, features, ease of configuration, security, etc. between 
the two?
