Unable to Connect to SMTP Host
« on: 2017-06-12, 19:44:33 »
Mxtoolbox produces an error Unable to Connect to SMTP Host. Ore Information About Smtp Connect
We attempted a connection to your mail server on port 25 but your server did not respond. More than likely there is no email server at this address or you have a misconfigured firewall or spam filtering system.

How to configure PTR record on one IP for several domains. Or how to create a HELO (EHLO) record on the server?

For PTR (aka RDNS/Reverse-DNS), ask to your provider to set it.
