Unfortunately whitelisting does not seem to be working here at all from the
milter...  Neither site-wide nor user_prefs nor database entries seem to
rate things...

Yes, I had noticed the size change... I knew it was from the additional
headers, but I had forgotton which one(s) would be modified... hmm....

I don't know which header is actually the one being checked for the
USER_IN_WHITELIST test, but the following headers contain the (in this case
domain) information that the user has whitelisted :-
>From  (yes, no : at the end there, this one is right at the top of the

Return-Path:
To:
Sender:
Errors-To:
X-BeenThere:
<the "standard" well-formed list headers, eg List-Id, List-Unsunscribe, etc)

And the user is using "whitelist_from  *<listdomain>" as the method of
checking....

Just I know (as I've got sort of some free time, I have quite a bit of time
to work on this though - I need the functionality working correctly), which
headers are added by sendmail before it hands it off to procmail?  I already
have one patch I need to write for spamass-milter (a patch to have it check
the local alias database for the local user instead of just sending the To:
user along to spamassassin - and a method of setting it so that it either
does not check outbound messages, or if it does, only ones to "local"
recipients).  Getting that sorted out is high in my list of priorities for
this setup (in fact it's top of my list at the moment).
