Should I setup DKIM, DMARC, SPF and reverse IP lookup?
This is no brainer to setup using mailcow. Just need to copy paste the provided TXT values from mailcow ui into your dns entries.
Mailcow is fantastic and very easy to deploy. I highly recommend it.
If your domain will NEVER send e-mail out, you only really need and SPF record to tell other servers to drop e-mail FROM your domain. Even that’s somewhat optional. If you ever plan on sending ANY outbound (you should at very least for the occasional ticket) then do DKIM, DMARC and SPF. The more of these you do, the less likely e-mails FROM your domain are to be flagged as spam.
Is there any other beginner-friendly email service I should read about?
If you don't want to setup everything as you should there's also https://mailinabox.email/ and https://docs.mailcow.email/
Wow! this is exactly what I needed. Although, I didn't exactly ask for it.
Thank you very much
