I want to be able to only allow a certain email to be sent from one of several

Currently im doing something like:
blacklist_from [email protected]
whitelist_from_rcvd [email protected] mail.foo.com
whitelist_from_rcvd [email protected] sales.foo.com
This doesn't really do what I want because the blacklist and whitelist scores
cancel each other out.
I saw talk in the past (2002?) about adding a unblacklist_from_rcvd
what I really want is a
blacklist_from [email protected]
unblacklist_from_rcvd [email protected] mail.foo.com
OR
only_allow_from_rcvd [email protected] mail.foo.com
What are my options for to accomplish this?
SA does not have any support for this.
The unblacklist commands do exist, but will only remove an entry that
they match *EXACTLY*. Their function is implemented as "if this is
found, delete it", and are intended to allow a user_prefs to completely
delete site-wide white/blacklist entries. They cannot be used to create
a blacklist with "holes" in it.
You can negate a blacklist with a whitelist, but the scores simply
offset, as you've seen.
It is possible to change the scores of the whitelist rule, to make it
larger in magnitude than the blacklist rule, and thus keeping some
negative score..
i.e: adding this to your local.cf:
score USER_IN_WHITELIST -120.000
Would cause any white/black overlap to result in a -20 score. However,
any whitelists without overlap would now get -120 instead of -100...
That may or may not be an issue for you, but it is one approach to the
problem you have.
see also man Mail::SpamAssassin::Conf:
unwhitelist_from_rcvd [email protected]
Used to override a default whitelist_from_rcvd entry, so for example
a distribution whitelist_from_rcvd can be overridden in a local.cf
file, or an individual user can override a whitelist_from_rcvd entry
in their own "user_prefs" file.
The specified email address has to match exactly the address
previously used in a whitelist_from_rcvd line.
