PSA: The Perils of an .xyz Domain (www.spotvirtual.com)

I finally got around to setting up the e-mails correctly for my instance (mander.xyz) and noticed that the e-mail deliver-ability is awful, as I get heavily penalized by spam filters for having an .xyz domain. I would not be surprised if search engines penalize this too.

It is not a simple task to change a domain name for an instance without breaking federation, so once you have a federating instance you are are stuck with that domain name.

I would not recommend picking an .xyz domain for your instances unless you intend it to be a private instance forever. If possible, try to go for a .com, or some other more standard TLD!

I'm not sure about how much it is penalized .xyz for being .xyz, but if the domain is new or you don't have DMARC, DKIM and all of those perfectly set, you will still keep having problems.

I was able to set everything correctly (DKIM, DMARC, PTR, SPF, MX records) and I can get a '8/10' from an e-mail tester.

The two points that are deducted are due to SpamAssassin flagging the TLD:

Even then, 8/10 should be good enough, but the emails go into the spam directly - at least for gmail and protonmail.

The article I linked goes into even worse cases, like admins blocking all of '.xyz' domains by default, social media sites flagging them as spam, and chat messages including an .xyz url being silently blocked.
