Let's encrypt has been free for a while.

Nvm that's for email

@Condor
Why are you doing that? Kinda bad

@Condor
Buy a cheap one, $20 for two years from namecheap. Your emailserver will fail DANE + MTA-STS :)

@Condor

You can solve DKIM very easy with amavis, it takes probably 4 minutes for you to fix that.

Also, iRedmail is maintainable. It uses standard components so resources are easy to find.

@Condor

Why do you do that to yourself? Use different selector for each server.

server1._domainkey.yourdomain.com

server2._domainkey.yourdomain.com

I dont know what kind of documentation you read.

@Condor

DKIM is for the sender domain only, and not the server. So if you use the server to send email for condor.com - you have to create keys for condor.com and not the servers hostname.

If you do

dig pepperoni._domainkey.linux.pizza TXT

and

dig calzone._domainkey.linux.pizza TXT

You will get two different keys. Thoose keys does not affect each other at all, but the selectors is different and you can easily configure what selector to use in your mailserver.

@Condor
I Love every kind of 🍕

@Condor
Btw, if you feel like that you dont want to host your own email server, you can have a place on mine :)

@Condor

Just hit me up! There is a few here that do that already, and hopefully they like it
