Listserv whitelisting: Reply-to header field?

[Brett Charbeneau]

 	Can anyone please offer me some tips on this? I've scoured the list 
archives and docs and have come up empty-handed.

SPECIFICS:
Debian 3.1, kernel 2.6.8,
Sendmail 8.13.4, MailScanner 4.41.3-2, SpamAssassin 3.0.3-2 (deb packages)

 	Several of my users subscribe to a listserv that consistently gets 
marked as SPAM and I'm having a hard time figuring out how to whitelist these 
messages.
 	The listserv creates headers that shows posts as coming from the poster, 
not the listserv server. This makes filtering on the "From:" field ineffective.
 	I tried to enter a rule in my

/etc/MailScanner/rules/spam.whitelist.rules

 	file to filter on the "Reply-To:" field like this:

Reply-To:       OCLC-Cataloging <OCLC-CAT at OCLC.ORG>     yes

 	but this isn't working either. I supply a sample of the header from this 
list below.
