Hi, > premium58.web-hosting.com is not your SMTP submission server: > > $ host premium58.web-hosting.com > premium58.web-hosting.com has address 198.54.120.203 > The server premium58.web-hosting.com is hosted by NameCheap and is used by many of their user as part of their server farm. All the IP you see in my domain are either the ones used by Namecheap for my dedicated IP or the IP of one of their server (ftp for example). The IP that www.cyrania.com or www.polynamaude.com is proxied thru Cloudflare, so does cyrani.com and polynamaude.com > What is this 162.213.253.79 IP address? The IP address 162.213.253.79 is the dedicated IP I rent from Namecheap. Can you control its reverse? > Good question, I'll need to go back read a bit on networking and DNS management. > Is cyrania.com a domain that you own? Yes, I own cyrania.com and polynamaude.com (the domain name used for the email I am sending). I know the SMTP server respond to the name CYRANIA.COM (HELO) but is relaying mail for polynamaude.com too. > This is a copy of the dump of my domain name config for CYRANIA.COM -------START ;; ;; Domain: cyrania.com. ;; Exported: 2021-02-05 22:27:25 ;; ;; This file is intended for use for informational and archival ;; purposes ONLY and MUST be edited before use on a production ;; DNS server.
