I'd say there is an increased chance of it. Pray nobody uses it in an
address comment...
What if someone is unsure of which domain a user is at:
From: stoopidaoler(_at_)aol(_dot_)com
To: dave(_at_)anything(_dot_)com, dave(_at_)anything(_dot_)net
Subject: Sorry dave, I can't remember which is your address
(assume for a moment that this is addressed to a user of yours, not to
someone who has the sense to disassociate AOL users).
Or multiple people are validly addressed:
To: validuser(_at_)anything(_dot_)com
Cc: drinkingbuddy(_at_)earthlink(_dot_)net
Do you think it would be a good idea to send anything addressed to (any
name here)@(any word here).net to bit hell
If that's the actual envelope recipient ("RCPT TO" in SMTP), then your MTA
should reject it since it isn't handling email for that domain (and if it
doesn't reject it, then your MTA is misconfigured). As a result, procmail
should never see the message -- for procmail to see it (as LDA or invoked
from .procmailrc), the message has to have been addressed to a local user.
If you're saying that just because a .net address appears in the TO: or CC:
fields, you're going to toss plenty of perfectly good email, because the
expression you give doesn't even necessitate that it's a .net variation of
your own domain.
assuming that if it was really intended for a user at my domain, it would
be properly addressed (with the .com extension?)
I take it you've never used, say, a mailing list? Please take a moment and
examine the headers of this message and tell me who I addressed it
to. Now, if the procmail list were hosted on a .net, would you be throwing
it away?
I know this won't catch all spam (as if there is a way to
catch it all), but this would probably catch a good chunk of it.
I think it'll catch a much bigger chunk of perfectly valid email.
Lastly, assuming this is a good idea, would this recipe work to accomplish
this?

* ^TO.*\.net
/dev/null
Really, really, really big suggestion: DO NOT file into /dev/null when
experimenting - even if you were to get confirmation that this was a good
idea (and it isn't), you should want to file the messages away so that you
at least have a CHANCE at pulling mis-hits out of the wastebin.
