Understanding mail concept

I could not find documentation about technical concept of mail within discourse. I’ve followed the simple installation instructions and configured variables using my gmx account. However, I did get any mail.

For me it’s confusing that I should configure SPF and DKIM while having credentials to login in a mail server. The former sounds like discourse is acting as MTA, the latter is acting as MUA.

Can someone please explain or heading me to appropriate documentation?


Well, if you want to send mail that’s what you have to do. If you have heard of unsolicited email, these are some things that have been done to mitigate it. Have a look at Troubleshooting email on a new Discourse install.
