I’m working on self hosting a e-cloud server ( for e/os phones). The mail server component of it wants to have a rDNS PTR record from my public IP back to mail.<myDomain.com>. I can’t do that since I’m using dDNS and my ISP won’t give me that ability unless I have business service (very expensive). The ISP I have is my only choice and I hate them. I have DNS Zones hoisted elsewhere to handle my dDNS scripts for everything but rDNS. So on tyo my question, Anyone know of a way to get a public IP service that will allow me to make a rDNS PTR entry and forward all traffic to my real public IP? Would that even work?
EDIT: Thanks everyone for the suggestions, I have considered VPS but I’m trying to save the extra cost of the VPS and also like the idea of having all my data where I can actually touch it. I was hoping for something like a reverse proxy service I could get with DNS and a static IP (so I could have rDNS) for cheaper than a VPS since I would not need the storage, CPU, etc.
Host your secure mail gateway on a service that lets you manage the ptr records. Alternatively outsource the SEG completely.
