Thanks Julian, I don't think the wildcard limitation is all that big of
a deal for me but it would be nice.  I am trying to mod the code a
little to add support for an "everybodyelse" black/whitelist.

Actually, my issue is mainly with blacklists.  I have a customer who is
on a crusade to wipe out *all* spam for his domain.  He sends me new
blacklist entries everyday.  The problem is that he's a bit overzealous
and I end up blocking sites for other customers who don't want it.  So,
my plan is...

1. Move all of his blacklist entries to his own config file in
.../by.domain/blacklist.  He has multiple domain names so I've created
logical links (ln -s) of those domain names to his main config file.

2. Will update the MailScanner.conf file with "Is Definitely Spam =
&ByDomainSpamBlacklist".

3. I would still like to have a global blacklist for everybody else so
I've created a file called ".../by.domain/all" that I can put global
entries in.

4. I've modified the code in CustomConfig.pm with these entries...

  return 1 if $BlackWhite->{all}{$from};
  return 1 if $BlackWhite->{all}{$fromdomain};
  return 1 if $BlackWhite->{all}{$ip};

  ...inserted right after your matching code.


Is this the right approach?  I handle several other domains and am
trying to avoid having to duplicate blacklist entries that I want to be
applied globally.  Thanks for all of your help.
