I'm trying to set up expiry of mailing lists using formail/procmail. I have
inserted a line in incoming messages to give an expiry date:


Expires: 2006-03-22

I'm now trying to get a procmail recipe to work on that line when it reaches
that date. I've tried:


DATE=`date +%F`

EXPIRY= "expires: "$DATE

:0
* ^List-Id:.*mythtv
* EXPIRY ??
        /dev/null
        
:0:
* ^List-Id:.*mythtv
        /var/spool/mailbox/mythtv


$EXPIRY contains what I want to search on, but how do I get it into the
condition field?

Any (non rude) suggestions greatfully received.
