I was thinking the filter itself could do the rejection, but yes, understood. Either way means some extra configuration is needed, either Postfix or filter. There is an advantage (or disadvantage, depending) of doing the PREPEND and rejecting in the content filter: this way, single- recipient mails to the spamtrap are rejected. Personally, I would want to do more with a spamtrap than this as alluded upthread. Your suggestion of a REDIRECT action would be better, because then content analysis can be done. > The check_recipient_access with DISCARD is probably easiest, but > the spamtrap address must be accepted by the pre-filter postfix. Got it. And I have reviewed and learned SMTPD_PROXY_README a bit better in the process.
