Although the fake-MX was discussed I think the discussion included a 
caveat that if you are going to use a fake-MX you need to use it for an 
IP address that is allocated and is controlled by you. Otherwise you 
open up the potential for real mail to do very strange things!!!
Use of a BOGON address might have been an idea, as long as it wasn't a 
BOGON that had special uses (e.g. RFC1918), however, there are no such 
BOGONs left anymore... the last allocatable IPs were given out this very 
week.

your dns server, the ip of your outbound nat (as long as it would never

yes, selecting a RANDOM ip would be bad.  someone might put an smtp

allowing anyone who is NOT under contract to you to potentially access

I'd say both. we're in war against spammers. if non-spammers take a
spammer attitude, then they are part of the problem.

if you want to catch silly ratware, then
- make your MX different from the A of your domain. some ratware will
connect to your A record.
- change your MX from time to to time. some rateware resolves the MX
before deployment
- setup a real second MX that defers all mail. sure you'll also block
qmail, but is that really a problem?

Right, but if you use an RFC-1918 address and your main MX's are down
for some reason, your mail might end up in some stranger's hands...
think about it.

Definitely a spam pattern.  Some logs with private info scrubbed
(these all publish an MX resolving to 127.0.0.1):

2011-01-03T00:04:18.230501-05:00
p0354G2P030889: what=rejected, city=Ludhiana, country_code=IN,

Those all look pretty spammy to me.  We also see some that publish
an MX resolving to 255.255.255.255.  Even the RFC-1918 ones look
pretty bogus to me from our logs.  Example:

2011-01-06T03:27:39.901570-05:00

Nothing wrong there. The host says helo mail.apache.org and...

$ host mail.apache.org
mail.apache.org has address 140.211.11.3

If you're going to verify HELO, you need to look up the name given in
the HELO. Whether the cost of a lookup is worth the benefit is a bit
questionable.

We score for impossible HELO names, like name with no dot. Those are
usually home Windows boxes, but look out, they can also be hosts at
small organizations with overworked or newbie system admins. I would
not block outright for that. As David said, lots of fps await.

Rejecting on that basis would also cause tons of false-positives.

A long time ago, I was involved with an argument with the RFC-Ignorant
maintainer.  The thread starts here:

http://lists.megacity.org/pipermail/rfci-discuss/2004-September/002668.html

The gist of my argument was that addresses that never *send* mail can
reasonably expect never to *receive* DSNs or other kinds of messages
with an envelope sender of  and can legitimately block them.

The battle raged for a while, but eventually we were delisted.
(We block mail from  to postmas...@roaringpenguin.com because we never,
ever send mail from postmas...@roaringpenguin.com)

Regards,

David.

J, I think the unfortunate part that Barton was referring to (the part 
that creates humor) is the joining of e-colli with a weight loss spam.


Getting e. coli is a quick way to loose weight, but a VERY unpleasant and 
rather grotesque way to do it.


(slightly gross, as this page describes the symtpoms of e. coli, but 
nothing too graphic:)

So, how would you like to try my new weight loss program, recognized by 
the CDC itself!


I dunno, I thought the mention of the Army Corps of Engineers and pumping in 
the same message as a lose weight message was pretty funny as well...

This is why you don't blindly filter for spam based on single, simple
