Does anyone know what generates mails like this:
----<Start of curious mail>----

The mentioned server is mine, and it properly rejects the mail(s). I've got
like 10.000 of them in my mail spool right now, and I'd like to know if
anyone knows the used program.
Another question: Does anyone know of a good way to purge the (sendmail)
mailspool from that crap? I can't purge by sender/recipient, but the subject
as well as the body (see above) are always identical. Just how to kill the
unwanted spool files?
I do know that I lately pissed a few spammers off royally (including death
threats and other funnies), so I am not surprised.
Thanks in advance
