... or a To: field that doesn't name you.
If the topmost Received: header of mail you get at newsguy.com mentions
worldnet, then likely it was forwarded. Do you want to differentiate
it from mail that originates on worldnet? (Do you get any mail that
originates on worldnet?)
Yes and yes
A further complication may be if I happen to send a test message
or something similar from my home machine to worldnet address. Since
my smtp server is worldnet it would then originate and be forwarded
from worldnet.
My first guess would be something like this, but it's probably not so great.
I'll have a better suggestion below.
:0:
# if it's addressed to worldnet, assume it was sent there (cheapo shortcut)
* ^TO_yourworldnetid(_at_)worldnet\(_dot_)att\(_dot_)net
worldnetforwards
That one for sure
:0E: # otherwise
# see if there are at least three Received: headers to weed out mail that
# came straight from its source without forwarding
* ^Received:(.+$)*Received:(.+$)*Received:
# suck up the topmost
* ^Received:\/.+
# check it for any mention of worldnet
* MATCH ?? worldnet\.att\.net
# and file if there is
worldnetforwards
This is probably getting close to the mark but, even direct mail has
several Received lines:

Better, I think, would be to forward your worldnet mail in such a way that
makes it identifiable. To you have plus-suffixing available on newsguy?
If so, you could change your .forward on worldnet to read something like
***8<snip
The AT&T account has a web interface to setup forwarding. The only
choices are the address to be forwarded to and whether to leave a copy
or not.
