No, after filtering IN the mailing list(s) I am subscribed to, I check all
daemon sent email for my "X-Loop:" header in the body.
#
# Check "Daemon"-sent email:
#
:0
* ^FROM_DAEMON
{
#
# Does the email contain my "X-Loop:" somewhere in it?
# If so, trash it:
#
:0BHD
* X-Loop: bodysurf
/dev/null
#
# If the email does NOT contain my "X-Loop:" in it, then
# filter it IN as it could be interesting:
#
:0E
$DEFAULT
}
However, even with inserting a "Precedence: junk" line, a "X-Loop:" header
check, and checking incoming email to see if it's daemon generated, I've
still run into loops!
One place in particular sent an autoresponse that stripped out the body
and headers, had no "Precedence: " header and no information from the
header that it was daemon-generated. One can only do so much :^(. Some
people I know have recipes set up to only accept/autoreply to a particular
address X amount of times, after that, they get dropped to "/dev/null" or
just stored in a file (but not autoreplied to).
Lates!
