Quoting Martijn Rijkeboer <mart...@bunix.org>:
Hi,
# incoming mail for our domains is relayed to "i-mail" server
accept from any for domain <domains> relay hostname i-mail
But this will also relay non existing mailboxes. Any suggestions for that?
Sure, put your list of addresses in spamd.alloweddomains (yes, it's
also for email addresses, not just domain names).
You can generate the list with an LDAP search or whatever and then scp
it to your spamd box. Not very difficult at all and it will cut down
your spam even further.
