I know I can get sendmail to run procmail on out going mail using the  
mailertable or putting a local_rule in the mc file, but I'm worried  
about what would happen when sendmail delivers mail to itself..  
Resulting some some horrible loop..

For example:
LOCAL_RULE_0
R$* < @ $+ .procmail. > $*  <tab>$@ $1<@$2.>$3   <tab>Already  
archived, map back
R$* < @ $+ .procmail > $*   <tab>$@ $1<@$2.>$3   <tab>Already  
archived, map back
R$* < @ $+. > $*    <tab>$#procmail $@ /etc/procmailrcs/rc.archive $:  
$1<@$2.procmail.>$3
R$* < @ $+ > $*     <tab>$#procmail $@ /etc/procmailrcs/rc.archive $:  
$1<@$2.procmail.>$3

Though that works on incoming and outgoing..

Or another example:
LOCAL_CONFIG
# add .PROCMAIL to the pseudo-domain list
CP.PROCMAIL
LOCAL_RULE_0
R$+ < @ $+ .procmail . >
	$#esmtp $@ $2 $: $1<@$2>
# match all other mail and send it to procmail script
R$+ < @ $+ . >
	$#procmail $@/etc/procmailrcs/rc.archive $:$1<@$2.procmail>

I would prefer to implement as much of it through the mailertable  
feature as possible though and I haven't seen any examples of doing  
that..

Also I don't want it to cause problems with local or incoming mails..

Anyone have some insights?
