Default Stop Spam from ISP Mailserver


I have a client, he receives a lot of spam from his ISP Mailserver.
Is there a way to limit spam using an OpenBSD Gateway with PF and Spamd at his place ? (His mailserver is ISP Mailserver, so he hasn't mailserver)

I think it is not possible, true ?
If you have an idea ...

I think this has already been answered twice on misc@.

spamd(8) works only between mail servers, and has nothing to do with mail clients.

Since you haven't yet read the man page, or, you don't understand it, let me try to explain:

spamd(8) pretends to be a mail server, and temporarily blocks incoming mail from other mail servers it has not seen mail from before. Robot platforms that spew spam do not usually bother to retry. Spamd only blocks these robots, it does not stop spam sent from a real mail server.


Once the mail has been retried a second time, spamd will tell PF to redirect the incoming mail to the real mail server.

Legitimate mail incoming from a previously unknown server will have to try three times to reach the real server.

Clients have nothing to do with spamd.
