Unable to start postfix

[damanmokha]

Hi,
i am using centos 7 with sentora 1.0.0

Postfix is down due to smtp port is not listing, rest of everything is working fine in sentora. Tried to restart the postfix shows following error

Job for postfix.service failed. See 'systemctl status postfix.service' and 'journalctl -xn' for details.

result for systemctl status postfix.service is

We need more infos. I have it running fine on centos 7.

Could you check more logs? Anything else on port 25?

Who is your ISP.
