need ability to block mail from a specific machine

[Jared Mauch]

spammers use a variety of techniques to hide their true
identiy. I have a remote MX host that they
periodically relay their spam through and due to its
configuration they periodically have messages that come
through with a From: <email address hidden>

I'd like the ability to mark for discard any mail that
is @MX.HOST
without having to guess the explicit addresses they
will be sending from. If this functionality exists,
please ignore my ignorance.

Yes, this functionality exists. It is possible to use python regexps in
the Sender
Filters (Privacy Options->Sender Filters->Non-member filters).
Example:
^.*@MX\.HOST$
