My ISP hand out static ip (4 and 6) and allows me to change rDNS too. So
i do run one of my mail servers from my home FTTH connection.

It also helps if you configure SPF and DKIM for your domain. Rejected
mails almost never happen, mostly only random by Microsoft O365 servers.

For those who ISP blocks port 25 you can configure your mailserver and
client to use port 465 (SSL) or 587 ((START)TLS) both with authentication.
