Re: variables in matches?

Mr. Guenther has answered your variable expansion question.  I'll offer a
handy recipe along similar lines:

I set $FROM (and some other oft-used variables) in my .procmailrc:

$FROM=`$FORMAIL -xFrom: `


:0
* $ ^Message-[Ii][Dd]:[         ]\<$FROM\>
{
        LOG="SPAM: MessageID *IS* FROM.$TWITVER"

        :0:
        |gzip -9fc >> $MAILDIR/twits.gz
}


This tosses messages in which the messageid is the same as the spam FROM
address, a trait I've been witnessing on several spams recently.
