I seem to be having some issues with delivery to Gmail. I have noticed some other threads on this, but I can’t seem to find anything in regards to multi-domain setup.
Here is some background:
primary domain: baxtmann.me
secondary domain: nukaco.in
I have set up PTR in my DNS for baxtmann .me. I have not for nukaco .in since I actually cannot. I use Cloudflare for DNS, and I can only create ptr’s for the domain itself (aka cannot create ptr on nukaco .in that points to box. baxtmann .me) . So I am wondering, how am I supposed to setup a ptr for this secondary domain? (note that on secondary domain I just have the mx set to point to box. baxtmann .me). On primary domain, I have both ipv4 and ipv6 (converted to nimble) with the arpa extension at the end as well.
Does anyone have insight on what I should do to configure this?
I appreciate it!
Let me know if you have any questions.
Note: Since I am a new user apparently I can only post 2 links so I added a bunch of spaces around some of the links here just to get past that. There is no spaces between the URLs in my dns or anything like that lol.
