    Issue Google put every mail into SPAM

    sweet-hoover.MY-Plesk-IP.plesk.page is not a valid hostname/FQDN for a server but a testing placeholder. Check reverse DNS and IP for your domain at your domain hoster. DNS/IP updates can take some minutes up to many hours.

    A server needs a valid hostname f.ex. server2.your-own-server-domin.tld, and the mail server needs to use something like mail.your-own-server-domin.tld. Can you understand what i mean?

    Its a problem that mxtoolbox highlights & it wasn't a problem on my old server with a reputable IP, but I have been forced to migrate to a new server with a new IP that is part of a block of IP's on a blacklist that I cannot get it removed from. I have managed to get the IP mitigated by MS but...

    Resolved Undelivered Mail Returned to Sender

    @Ddungu Most large mail hosters block servers which have no valid hostname (FQDN, check DNS MX entry) and use instead a generic hostname like yours. You use plesk-12703529.cloudfabric.net instead of mail.mydomain.ork (subdomain of you domain).

    Issue Google put every mail into SPAM

    With MXToolbox, the rDNS of my IP just returns sweet-hoover.MY-Plesk-IP.plesk.page and reports it correct. Furthermore, I repeat, my Full Hostname is reported to me as an error by Mail-Tester and instead it is this name that is suggested to me

    Resolved SMTP - Reverse DNS is not a valid Hostname

    I have run into the same problem and checked the RFCs, but found nothing that would require a 3rd level. See also Definition of Fully qualified domain name. So I'm pretty sure this is mxtoolbox overreacting.

    Resolved SMTP - Reverse DNS is not a valid Hostname

    This is from the result from a mxtoolbox test right? Are you also having trouble with sending email or are you only concerned with the warning from the mxtoolbox test? From what I can gather this warning can often be ignored as it does necessarily indicate a problem. You're DNS records seem...
