If you are referring this problem, Philip; it came up sometime ago
when a few tried to see why exim became an open relay when run from
inetd. This however did not effect other OS's such a OpenBSD(I checked
this)....

Very True.

However, I feel compelled to rant about the support via inetd. Simply
put, I dislike it...but I guess that's just IMHO. However, is there a
reason to have support via inetd in the first place? Other than the
fact that you may wish to run a MTA out of inetd/xinetd due to limited
system resources...but if you don't have enough resources, why run a
MTA in the first place...

Its trivial to crash inetd via a nice DoS (I've sent a few mails
regarding this to netbsd@/openbsd@), and xinetd is nicer but not
really a good option to run a mail server....
