Not to play the obvious, but have you tried contacting Hotmail about this?
I'm sure they have a # for ISPs to call in regards to mail problems (just an
assumption though, I haven't checked myself). I had to call AOL about them
blocking some of my servers - took them a week to get back to me (meanwhile
about 4-5 of our servers were blacklisted by them :P), and when they got
ahold of me they didn't give me much of any information about what even
prompted the black hole (gave some excuse about not having an abuse address,
even though we did - they to this date have yet to send us any email to our
abuse address even though I made sure to tell them what it was).
It's worth a shot. Just come off sounding like a System Admin for some
company (might want a website to seem somewhat legit) and they should be
somewhat compelled to help out.
Eli.

Subject: [Exim] How to deal with Hotmail
I have a difficult problem on one of my exim servers. Hotmail accepts
mail coming from my users, but the mail never gets delivered. It just
gets blackholed. The server isn't listed on any public DNSBL's, but it
is serving from DSL (SBC). The other server, which runs the same
version of exim, is also on DSL, but it is on Speakeasy.
My two best guesses as to what's going on are:
1) Hotmail has a problem with the SBC DSL server having a different
reverse DNS lookup (the IP resolves to
adsl-66-122-112-170.dsl.snfc21.pacbell.net. but the forward resolves to
dina.mrtoads.com.)
If this was the case, wouldn't the Hotmail server issue some complaint
and refuse the mail?
2) Hotmail decided to block SBC DSL IP's, but not Speakeasy DSL IP's.
This would seem to be a bit weird, but perhaps they have had spam
trouble from SBC.
Does anyone have any insight into the mysterious and annoying workings
of Hotmail?
