No. Don't do it. At the very least it'll get you listed on ORBS, which
checks for this.

I keep meaning to look at authenticated SMTP; though I'll be doing it
with with exim or qmail. Rather than POP before SMTP relay I'm going to
go for SMTP AUTH though, which Exim seems to do fairly easily and qmail
can do with a simple patch.
