RE: [Nolug] running a mail server with a Cox account

Hi Scott.

But mine doesn't match! You are saying that AOL only does a partial match?
Hmmm... OK, that would indeed allow mine to work but I don't see the
advantage to that method vs simply requite that there be some (any) revere
lookup name.

No. I assure you that AOL requires the domain part of the reverse
lookup to match. Call their NOC and ask. I did. At one time, they
briefly flirted with making the entire fq hostname match. You may
be able to find some old archives of inet-access that talk about this.

your mailserver announces itself as mail.sstar.com and that reverses
to sr.sstar.com. If it reverse to sr.johnsotherdomain.com, AOL would
silently /dev/null the incoming mail. I've tested this many times.

That's why I say to folks on DSL/cable who wish to send their own
mail via a local mailserver to simply match their hostname in their
mail server config to their ISP-managed public IP's reverse lookup.
