per recipient email address directives

[fugee]

Is there a way to configure a particular email address to only accept
mail from another particular email address or list, or host, whatever
I'm looking for a way to apply these kinds of settings to just a
particular email address The address is subscribed to a mailing list and
should only receive mail from that list and no other sender

[Luuk]

Should be possible with procmail

:0
* !^From:.*parti...@example.com
/dev/null

(above is untested!)


note: email is received from every address, but send to /dev/null for
all addresses expect the specified one.

Is there some header unique the list? maildrop or dovecot's sieve could
do the job by simply discarding mail without that header.
