No, in that situation greylisting would be contra productive. Real time sender verification with your Postfix. I use it for fetchmailed mail with milter-sender integrated into Sendmail. It saves me from a lot of SPAM because many if not most senders of SPAM is faked and thus not existing. This way, with sender address verification the mail is simply discarded. An example from my logs: Milter: to=<fetchmail@xxxxxxxxxxxxxxxxxx>, reject=550 5.7.1 recipient denied, because MX 10 'Vent.mokrohajska-school.sk.' [193.87.162.1] for <pkramervb@xxxxxxxxxxxxxxxxxxxxx> rejected sender.
