I’m looking to self host Mailcow at home. As I was looking into this I realised I won’t be able to set PTR (reverse DNS) on my home IP (ISP does not allow this). I already have Amazon SES setup and verified for the domain I want to use. When I set this up (SES) Amazon automatically created the DNS records, as the hosted zone is in Route53.
Before I go and launch Mailcow, which DNS records will need to point to my home IP to allow incoming mail to be received? I believe I would configure SES to be the mail relay once Mailcow is up and running. I’d like Mailcow to automatically get the certs through Lets Encrypt, but I’m not sure which DNS records I need to add/change to be my home IP.
