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.

To me it’s the reciever that unjustly blocks the mail, not our TLD’s that are “untrustworthy”.
Oh, absolutely.
I also tried setting up my e-mail server at home, but my ISP won’t let me forward port 25.
I think it is related to this. I also have a really high trust value an email tester and I use a .com. It doesn’t really matter. The email service we have on our company must have some kind of whitelist of “trustworthy” mail servers. I have sent emails to my company address and they go to SPAM. I’m pretty sure the whitelist is pretty small, or at least it doesn’t include email services provided by non big companies. I use Migadu, btw.
Linkedin blocks .ml website domains too. Rip any site that uses that I guess
In what way? I just tried sending lemmy.ml in a private message and at least that went through.
Did you confirm if the recipient got it? I shared a Lemmy post link via Linkedin DMs once and the message was shadow un-received (I could see it as sent but the other person never got it, only my before and after messages)
Yes, I sent it to someone who is sitting next to me. Maybe whatever algorithm they use for filtering is a bit noisy.

There are email providers who will block email from brand new domain names, and perhaps others will consider it spam, and maybe only consider it spam for the very first email contact between your instance and their email server. Your results may be better within a few weeks time.
I hope that’s the case! I will run more tests in a few weeks.
Interesting read. I just bought my wife a .garden to use for email. It’s on the more expensive side at $30 a year so maybe will avoid the same fate
