Procmail LDA "Received: from" headers

2000-01-22 01:10:26
  My new ISP uses procmail as LDA.  I'm trying to get my procmail
filter to handle that properly, without breaking its parsing of
sendmail and Exim headers (Now *THAT* is "fun").  My "sample set"
is rather small, and applies only to my ISP.  Here is a sample...

Received: from cac3.hub.mail.psi.ca(154.11.168.213)
 via SMTP by xxxxxxxx.xxx, id smtpd07151a; Wed Jan 19 23:48:19 2000

  Does procmail (in LDA mode) always generate such a header?  It looks
like the rule is...
 ^Received: from (${rDNS}|UNKNOWN)\([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+\)
  where ${rDNS} is the reverse-DNS.

  And out of general curiousity.  When is IPv6 coming out and are
there any sample emails for people to play with.  I suspect that
it'll probably break lots of stuff.
