Greetings,
I am running Exim on a Linux box and want to use a (.forward) filter
file to bounce any message which has more than 5 '@' symbols (ie
6 or more recepients).
So far I've come up with:
========
# Exim filter <<== do not edit or remove this line!
if error_message then finish endif
if ${sg{$header_to:,$header_cc:}{\n}{}} matches "(*\@*){6,}" then
seen mail
from "postmaster@???"
bcc "postmaster@???"
subject "Bounced message"
text "Some of our addresses do not accept messages with
more than 5 receipients.\n\nYour message dated: $tod_full\nwith
subject: $header_subject\nfailed."
save $home/bounced_messages
endif
========
in the .forward file. It works if I substitute a "," for the "@", but if I
escape the "@" with "\", it doesn't seem to work. Obviously I need
a little help with regular expressions. Or can anyone suggest a
better way of doing this?
This is to block certain "friends" who take great delight in
forwarding round those joke-lists and other such band-width
hogging penc. $deity knows I've tried telling them, but this seems
to be the only way to get the message through. It doesn't help that
SWMBO doesn't want me to block them at the SMTP port. <sigh>
