Right you are. My statement was a little inaccurate in that if you don't use 
the MX, you aren't using DNS for the normal delivery to a domain. Maybe I'm 
misreading my maillog. My nsswitch.conf has "files, dns" in it, so it should 
be reading "hosts".  The log entry indicates using the public address for 
the relay, but this is for the delivery of the message. MD may be doing 
something different during the check of valid users. I doubt it though.

Anyway, based on my previous example of how I am using this subroutine, what 
should I put into my $relay variable to make it use the address? Or better 
yet, where does it tell me what I am using when this is performed?

Thanks for the help.

Steve
