Are they all from MSN ? I have a handful of ISP domains for which I
doublecheck the domain in the From: against the domain portion in the
Message-ID: MSN, CIS, AOL, Genie, Prodigy, Earthlink, and others. These
ISPs I figure aren't likely to have users who are using OTHER mail servers
to relay their mail. And if anything valid gets blasted by this, I file my
junkmail anyway, so I can retrieve a copy if necessary.
That doesn't answer your question, but I thought I'd note it anyway.
addresses have all been of this format, but differing lenghts. How likely
* ^(From|(Reply-)?To):[ ]+[0-9]+[a-z]+[0-9]+@
I'd replace [a-z] with [A-Za-z] just to be on the complete side (otherwise
the first message with an uppercase letter in there is going to slip
through). Also, I might double up the numerics on either end (for "2 or
more" : "[0-9][0-9]+"), if this is a characteristic of the messages, though
I agree that I'd be unlikely to get messages with addressing matching the
basic format, so why bother narrowing the match?

Please DO NOT carbon me on list replies. I'll get my copy from the list.
