efa behind another antispam

Post by glf » 27 Feb 2019 16:52

Hello,
i've configured efa behind another antispam (I've just a external Ip address and I need to use another antispam for some domains and efa for each others).
So I've first antispam that send all emails for a efa managed domains but I'm getting this error:

EFA_IP] said: 450 4.7.1 Client host rejected: cannot find your reverse hostname,

How can I allow relay from MyAnotherAntispamIP ??

Thanks!

Hi,

have you tried to add your first antispam server into local networks in Postfix?
Webmin--->Server---->Postfix Mail Server---->General Options----->Local Networks
inside you should find localhost IP, and try to add, after, the public ip of first antispam server.

thanks for you answer.
Antispam1 and Antispam2 (EFA) is on the same subnet; they are seen through private ip

(host 192.168.1.41[192.168.1.41] said: 450 4.7.1 Client host rejected: cannot find your reverse hostname, [192.168.1.31] (in reply to RCPT TO command))

thanks

Try to write the other IP (even if in the same subnet) here:
Webmin--->Server---->Postfix Mail Server---->General Options----->Local Networks
should be 127.0.0.1 192.168.1.31
