I'm seeking a script or tool for a specific anti-spam use case:

  - read incoming mail in /var/mail/$USER (mbox format, of course)

  - if header Message-ID: line ends in ".amazonses.com and the
    address in the From: is from a domain that is not registered,
    then put the message in $HOME/mail/spam (mbox format)

  - else retain the message in /var/mail/$USER (mbox format)

Apparently a really nasty spammer got hold of my real (not
spamtrap42) email address and has been sending a few messages per
day, some of the with subject lines I consider offensive.
Unfortunately, some legitimate businesses still use Amazon SES
(despite their lousy reputation for coddling spammers), so I
can't filter just on Message-ID being from amazonses.com

More details:

I use MX Route as my email service provider (after the previous
provider closed down), with fetchmail periodically pulling from
MX Route and sending to procmail to archive and deliver.  I don't
want to change the fetchmail->procmail setup, so I need to filter
after delivery to /var/mail/$USER.  There are some Python
libraries that support mbox format, so I'll plan to write my own
script if a lower-cost solution isn't available.

Thanks.
