I have a whitelist of users who are allowed to receive mail and use
filter_recipient() to check it. Less than 10 lines of perl code :)
Or use sendmail's BLACKLIST_RECIPIENTS and access database.
For me, the main drawback of runing it in a mail gateway is that I
haven't found a way to train the Bayes filters in the gateway.
