Very true. :) Also, since you don't care about the trailing string,
don't make procmail waste effort on matching it. Just drop the trailing
"any char, and number of times".
You're using the correct approach to exempt specific messages from
matching the filter. However, if you are using server-side filters
delivering these internal messages to dedicated folders, you could just
as well change the order of the procmail receipts. First deliver those
messages that you don't want to be scanned by SA, then call SA for the
rest of the bulk that hasn't been delivered yet...
General note: If you feel the need to run SA, you most likely want to
use spamc/spamd instead of spawning a costly spamassassin process for
every mail to scan.
