Now I am not changing the SMTP default port and it’s running under port 25. I have given the fully-qualified domain name that mailcow.mydomain.com
I have also mapped the MX and txt value into the domain provider that like below
record = MX, host = @, points to = mailcow.mydomain.com
record = txt, host = @, txt value = v=spf1 mx all.
Here I am not using the default mailcow docker Nginx. I am separately installed the Nginx and wrote the config file for my domain. Also not add the ssl for my domain.
still, I can’t receive any emails from GMAIL and others. But I can able to send it.
These are the errors.
Please fix my issue.
