Karen,

This is something that I brought up on the list awhile back with how to
avoid this.  As we were getting hammered with spam getting to the end user
cause they were tagging the whitelisted postmaster account to it.

We do not whitelist the postmaster account, instead you setup a "filter"
test that contains an "allrecips" for the postmasters email address and
assign this test a really high negative value to prevent the message from
being bounced.  Then you set the action up for the test as a "routeto" back
to the postmasters account.

What this does is the following

[1] Allows all messages regardless of how many spam tests they fail to
always be routed to the postmaster
[2] If the message contains a user account other than the postmaster the
mail will be delivered to the user if the message is under your spam
threshold and if it is over your spam threshold whatever action you have
specified will then be enacted on that message.

We've been getting a lot of spam in the last week or so that bypasses all
our spam filters -- they are all copied to the postmaster@ account for our
domain.  Apparently, they are taking advantage of the common practice of
whitelisting the postmaster and the inability of spam filtering programs to
separate actions on messages sent to multiple users.  No doubt, it won't be
long before most messages do the same, rendering both your postmaster
account and spam filters useless.

I know it has been asked for before and said to be "impossible" (programmer
speak, for don't want to do it -- I know, being one), but PLEASE consider
creating multiple copies of messages that arrive for multiple recipients, so
that the spam filters can operate (yes, this means some complications, but a
little trickery could reduce problems -- for example, only making a copy for
the recipient(s) that are whitelisted).
