Careful with the RFCHeader blocker - you can't control its behavior. You
can only block, at SMTP level, and if for any reason a list message (from
this list or several others) match the line you blocked, you or your
users will be unsubscribed.

So be very careful with the strings you block.

With a rule and the free (or pro) regexmatcher filter, you can at least
control how the block is made, you can discard or quarantine instead of
reject, you can whitelist somme addresses.

The plan is to be very stingy with what gets put in that list since the
options are scarce.  Already saw 3 Vaigra blocks.

Does regexmatcher filter work on a server that is Mac PPC based ?
