Subject: new kind of spam (apparently from mailer daemon)


I have just found a new kind of spam which went through our spamassassin (actually it got a "banned" notification - we quarantine spam and virus but let banned be delivered).

The subject was "Delivery reports about your e-mail", the apparent originator was From: "MAILER-DAEMON" <nore...@ourdomain>, the body was empty and there was a single attachment "transcript.zip".

There are only two Received lines in the header as seen on my destination machine (I've edited out the local details):

Received: from our_mx by my_machine for my_address
Received: from ourdomain (localhost [113.167.75.53] (may be forged)by our_mx

So it looks like the spammer connected directly to our mx (one of two), faking its name as our domain.

To users it seems a strange mailer daemon message, since our mx are linux boxes and do not send zipped reports. So it is obvious spam.

My question is : is it ok to feed it into the sa-learn crontab we use for spam which escapes spamassassin, or the way it is forged will cause problems (e.g. filtering legitimate mailer daemon reports ?)
