I've been using SA and other software for few years for antispam gateway.
During first few month, the results was very good, most spam was
rejected and finaly SA examine the rest.
However, after almost 2 years now, the spam rate received by user are
high, so I think that I have to change the way we react to spammers.
Right now Im using Postfix, DNSBL, sqlgrey and spampd+SA.
I need input to build a new antispam gateway that can adapt to a new
spam technics.
I would highly appreciate any inputs. TIA
Regards,
