[TriLUG] OT: DSL for SOHO in Chapel Hill

[Carl Lindner]

Joseph and Tanner, thanks.

I've been looking at my postfix config and haven't spotted anything that 
is a giveaway for configuring it as a secondary MX.  I'm assuming 
something special would have to be done because a stock Postfix setup 
typically doesn't accept email for users it knows nothing about.... 
With that in mind, where could I go for more specifics on how to 
implement this (just in case i miss something good in my google searches)

thanks
