Hello guys: I'm an old spamassassin user but not an experienced one indeed. I have a Zimbra server and a dedicated antispam with MailScanner like this:
Zimbra: 192.168.1.25 Antispam: 192.168.1.5 All incoming and outgoing mail traffic goes through my antispam box. Well, I have already working DNS based checks like "skip_rbl_checks 0" and/or "RDNS_NONE" working fine for external mail servers. However, I don't know how to make an exclusion for my internal network (192.168.1.0/24). On my Antispam box this is what I tried to put in /etc/mail/spamassassin/MailScanner.cf: skip_rbl_checks 0 trusted_networks 127.0.0.1 192.168.1.0/24 internal_networks 192.168.1.25 I've configured a local named service on my antispam box to make sure that 192.168.1.5 and 192.168.1.25 have a correct rDNS configuration (in both directions). I even configured local resolution of those IPs in /etc/hosts However, I can see that SpamAssassin is still scoring all my outgoing emails like this: RDNS_NONE 0.97 RCVD_IN_BRBL_LASTEXT 1.45 How can I effectively avoid these kind of DNS checks for my LAN? Thanks in advance.
