I am in the process of debugging an application to Postfix error and thus have occasion to have the maillog tailed in a session window. The vast, vast majority of the traffic I see is spam and attempted spam most of which is being handled by amavis-new and spamassasin.
Does the idea of configuring Postfix so that external (to our network) smtp connections are only accepted from servers identified with MX records for the connecting IP address make any sense? Is it possible? -- *** E-Mail is NOT a SECURE channel *** James B.
