Hello
I have a spam assassin server setup on postfix and I can scan mails from mail clients configured with the server as the smtp outgoing settings but when I change the settings to smtp.mail.yahoo.com the mail is sent without being scanned by the server and there is no log of the transcation in /var/log/maillog. The spam server is sitting in front of a firewall that redirects all port 25 traffic through it. Pleas I need assistance urgently.
