Fixing that AOL thing for Postfix?

[dmorin at morinfamily.com (Duane Morin)]

Hi all,

Sorry for not paying attention a week ago.  Can somebody point me to the 
fix for AOL's ban of Comcast mail?  I googled around and just found a bunch 
of people that said "add smarthost=smtp.comcast.net" to sendmail.mc.  The 
thing is, I'm using postfix.  IT doesn't appear that sendmail.mc is 
relevant to me.  Help?

Thanks!

Duane
