Topic: Mail delivery failure to gmail and other mail servers

I have configured iredmail server locally on our office server.
Configuration was successful and all service is running properly.
But when I am trying to send mails to gmail or any other mail server; it reverts back saying : The IP is not authorized to send mails to our server.
I have created TXT and A record on domain hosting dns server and verification is also successful by google postmaster tools.
But, still same 550 error.
It is saying to get SMTP relays.

- Linux/BSD distribution name and version:  CentOS 7
- Store mail accounts in which backend (LDAP/MySQL/PGSQL):  PostgreSQL

Re: Mail delivery failure to gmail and other mail servers

I had that problem, too. You have to make the _dmarc line in the DNS entry. Some instructions are available on the Internet in various languages. I used one in german.

Re: Mail delivery failure to gmail and other mail servers

Now I have fixed some issues, so i can send mails to any domain-based mail id's but not to Gmail as it saying to use SMTP relays.
But I cannot receive mails from any mail id,, host unreachable error occurs.

Please add your server IP in the SPF DNS record of your mail domain.

Re: Mail delivery failure to gmail and other mail servers

Is network port 25 blocked by your ISP?
