Time without being here, greetings.
I have a problem with sending mail on one of my mail servers.
I am going to give you some details, I have pfsense installed with a public ip wan, but I also have 4 virtual ips (alias) there, each one active. WAN example with 18.104.22.168, the virtual ip would be 122, 123, 124, 125, one for each domain I have, ok!
Well then, I already configured an output ip for the first domain and the mail goes out correctly through this ip, which would be the main ip (121), everything is correct. Installed everything fine without problems, configured with nginx and proxy_pass and php-fpm. I can send and receive emails to gmail and hotmail, and internal in the same network.
I go to the second domain, configured in the same way, with the second ip (122), internally emails are sent and received, from 121 to 122 and vice versa, but the big problem is, if I want to send to gmail all the emails come out by the main ip, 121 and not by 122 which is what it is supposed to. Gmail gives me an error message that says:
host gmail-smtp-in.l.google.com[22.214.171.124] said:
550-5.7.25 [126.96.36.199] The IP address sending this message does not
have a 550-5.7.25 PTR record setup, or the corresponding forward DNS entry
does not 550-5.7.25 point to the sending IP.
Please, can you help me, tell me what could be the problem? The configurations of each mail server are correct, verified and I don't see an error in the logs, only that from the second server emails are sent from the main pfsense ip and not from the alias ip.
Thanks in advance for any help you can give me.
