Ah, yes. I had to deal with this one over the weekend. I was fortunate in
my decision to dump sendmail for smail a long time ago. With smail, you
can tell it only to do a hostname lookup if the domain is known (i.e. I can
list which domains to do a hostname lookup of) and I specify only our
internal domain as known. This way mail to the inside domain gets looked
up and passed via SMTP but mail to all other domains is routed to the
Very slick, thanx Smail guys.
