Any suggestions on how to block specific IPs? My SMTP server is being attacted by spammers. I'm getting hundreds of emails an hour from hinet.net and others where I'm not the recpient. It's like I'm being used as a relay even though I'm using the anti-relay protection feature and ordb.org filter.
A typical header:
Received: From edm100 (unverified [61.230.110.123]) by SMTP Server [192.168.1.20]
(WinGate SMTP Receiver v5.0.4) with SMTP id <0000165675@jparchitects.com>;
