I’ve heard that enabling CloudFlare DDoS protection on Lemmy breaks federation due to the amount of ActivityPub traffic.

You need to get a cert from Let’s Encrypt (using certbot), then look up directions for configuring nginx to use the cert files generated by certbot.

There are only 3 hard problems in programming:

0: Cache invalidation
2: Race conditions
1: Naming things
3: Off-by-one errors

You don’t need a mail server if all you want is a custom email domain. You can just use something like CloudFlare DNS to have them forward all emails to your domain to another private email address (e.g. Gmail).
