Here's the rub: When I send something to my own list, the listserver then
tries to send me a copy (since I am a listmember). But in response to list
traffic, the recipe shown above seems to match on the *sender*, creating a
mail loop. This is relatively benign--the listserver does not try to
Are you sure it isn't matching on the original To: from the original
message, or is the address list rewritten? In normal list serving
situations, the recipients are recieving the message with it "To: list".
If you're forwarding messages that are addressed to a list, and recieving
those same messages again, then of course you're going to be forwarding the
messages when you see them again.
That would, as expected, generate a mail loop.
If your list server inserts other headers (or better, if you can ADD and
X-Loop header, you can revise your recipe:
:0
* ^TOxj-list
* !^X-Loop:.*xj-list
! admin(_at_)crossroads(_dot_)net
The additional line says:
if NOT (starting from beginning of line)X-Loop:(any number of
characters)xj-list
So that becomes, if "to the list, and not "been at the list (i.e. delivered
FROM the list)", then forward it to the list, otherwise hand it to me.
If you can't change the list server config, try:
* !^Resent-From:(_dot_)*admin(_at_)crossroads(_dot_)net
(as appropriate to an ACTUAL header created by the list processor which is
unique to it).
Not seeing the headers from a typical message, or one of the looped
messages, I can't say what your server is providing that would be
triggering the ^TO regexp, but there are a variety of headers checked.
Have you tried enabling verbose logging?
VERBOSE=on
LOGFILE=$MAILDIR/log
Let the system process a few messages (to you, say, with the alternate
pre-filter you mentioned), and then examine the log. This will provide a
lot of insight as to what it is actually matching on.

"the latest version" is not an accurrate technical statement. Provide an
actual version number for reference. run 'procmail -v' to get the version.

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