Ok right now there is an expansion of the spam and high scoring spam score
that allows for the score for spam/high scoring spam to be configure via a
rule file. if the following rules were in that file:
To: me at mine.com 5.0
To: you at mine.com 7.5
FromOrTo: default 6.0
and a message arrived from they at them.com that scored 6.5, me at mine.com would
not receive the message but you at mine.com would. You would now remove
me at mine.com from the recipients list (and presumably CC/BCC)
Now suppose you were to also expand the whitelist/blacklist prior to
performing the deletion and that and the *whitelist* rules contained
To: me at mine.com and From: they at them.com yes
ToOrFrom: default no
Now even, though the message scored above me at mine.com's spam threshold it
would not be tagged /processed as spam and they would not be deleted from
the recipient listing. The inverse would be true for a mail scoring below
their spam threshold but the to/from pair expansion of the blacklist rule
set resulted in the sender address/host being yes.
This would result in the whitelist/blacklisting being as per user as the
spam/high spam scoring, yes? Of course the most economical processing would
be to test the message before processing through SA and see if the entire
message would be whitelisted or blacklist and process it accordingly (skip
SA or dump entirely) before wasting time with SA and/or virus testing, and
only do the above checks if there are more than one recipient.
This message has been scanned for viruses and
dangerous content by MailScanner, and is
believed to be clean.
