We have enabled SMPT Proxy in our UTM SG 430 firmware 9.4 but we are still receiving some SPAM e-mails. The antispam on the UTM is configured mostly with default options, any idea what could we add to the default config for antispam so that we could get a better protection from those obvious SPAM e-mails.
Maybe adding Extra RBL would help, if so what would be the list of those RBLs to add?
Thanks.
