When composing MIME messages with exmh's built-in editor, it sometimes
puts the .signature in the middle of the message, rather than at the end as
it should.

This example is not so bad - because the .sig ended up in the middle of a
text section - but I've previously seen it turn up in the middle of a 4Mb
base64 attachment.

This example was from exmh-2.1.1, but I've seen it happen (albeit very
rarely) from exmh-2.0.0 onwards. It's not easy to reproduce it, though.

Offending message follows:

This is a multipart MIME message.

Rhys, if the person you were talking to wants to see the headers after
seeing
the explanation of why the mail loop happens, then they're obviously
clueless,
so they're not someone who you want to be touching your mail system.

Please could you put me in touch with someone who's actually qualified for
the
job they're doing instead. I appreciate that front line support people have
to
deal with so many stupid queries that it's not worth employing people who
really know what they're doing, but surely you have _someone_ there with a
clue?

The fix to two of your problems is simple:
	1. Make sure your autoresponder doesn't respond to error messages.
	2. Make sure your autoresponder's responses have error message status
		so that nothing else will autoreply to them.

This is a universally-accepted solution which prevents such mail loops, and
frankly I'm amazed that whoever set this up didn't know enough to do it
right
in the first place.

The fix to the third involves a little more thought - but read
	http://www.linx.net/events/talk_mansfield.html
and	http://www.linx.net/noncore/bcp/ube-bcp.html

... and consider my suggestion that you start using ORBS on your own mail
relays, at least for mail outgoing from your customers - to protect your
offending customers from causing inconvenience to your innocent customers
by
landing you in the blacklists yourself.

Here are the headers again anyway.

Your mail entitled: "Re: [Ticket ID #1999111727] Re:Mail loops caused by
your
    autoresponder and listing in ORBS."
is suspected of being spam. It has been delivered, but rather than
going into the recipient's inbox, it has been stored in a
"Suspected Spam" mail folder which may not be read for some time,
if ever. There is no need to resend the message unless you have fixed
your server and would like your message to receive immediate attention.

This probably happened because your mail server is misconfigured,
and is listed on an Internet-wide blacklist.

You should be aware that many computers on the Internet will simply
refuse to accept your mail at all.

The exact reason why your mail has been flagged in this way is:
	Open relay - see http://www.orbs.org/verify.cgi?address=194.177.174.244
