[Mimedefang] OT: outsource email providers that "don't play well with others"

[Philip Prindeville]

I noticed that I was being spammed by some
clearwire-dns.net addresses.  So I contacted the
ARIN abuse mailbox for this address.  It pointed to
abuse at clearwire.net (apparently it should point to
abuse at clearwire.com, as this points to the corporate
mailboxes on the corporate servers).

When I emailed to it, I got:

--l434rQgo020620.1178168006/mail.redfish-solutions.com

The original message was received at Wed, 2 May 2007 22:53:22 -0600

Holy cow!

Could that message be any more misinformative?  Or ambiguous?  Or
just plain wrong?

The message did indeed comply with all required standards, as I'm
using Sendmail 8.13.8 and Thunderbird 1.5.0.10, both of which are
well-behaved software that generate correctly formatted messages.

So when I tried to look up ARIN the contact info for the MTA that
bounced this, I got a phone number that isn't answered, has no
voice mail, etc.

So I emailed them.

Didn't hear back, a day later.

Went to their website.  It's a single page, with an abuse, a support,
and a sales mailbox.

None of which are answered.

And a major carrier like Clearwire is outsourcing user email to
this company.

Not a clueful decision.

Has anyone else had runnings with InternetNamesForBusiness.com?

And would blacklisting permanently all their CIDR blocks for being
poor network citizens be wrong?

What do the RBL's say about them?
