If you mean "set up an equivalent service" under your own domain, that's both less private and more likely to be blocked; there are a lot of services which, unfortunately, only allow sign-ups from big, well-known domains.

Are there really? I don't think I've ever encountered such a service in all the years I've been using an email address under my own domain. And blocking every email address that's not from a big provider means blocking basically everyone who tries to sign up with their company email, which might not be great for business.

I've been running my own mailserver on a firstnamelastname.com domain for nearly 15 years.

As far as I can tell, nobody blocks it. Google sometimes rejects emails where the from address doesn't match the real sending address, which is fair.

I guess the first couple of years were rocky, I hadn't figured out DKIM and SPF and all the other blood rituals yet. Back then I got blocked by Steam and banks. But ever since I set up the correct security it's been fine. Been my primary email for a long long time. All my online accounts are tied to it.

Incidentally, I also have free and unlimited aliases. But I don't usually bother because I have a rule to route all messages to unknown addresses into a special folder. I can give out any random address at my domain and it will always make it back to me. So much more convenient than logging into the website to generate an alias.

I did that too years ago, but the management of it was kind of annoying. DKIM was just getting introduced when I stopped using it. SPF had controversy. I understand both of those are awesome now.

The biggest issue was if your ip address got listed in a RBL (Realtime Blackhole List), and then nobody would talk to you. Some were easy to get off, others were permanent blocks, and I found those to be constantly interfering with the delivery of mail. At least the rejection would usually tell you which RBL blocked you.

		Most RBLs are scams. No competent mail admin uses them to block mail ever.

I recently tried signing up for DeepSeek using my custom-domain e-mail address and the website said the domain is “not supported”.

Camel camel camel wouldn’t send notifications to my hidden email. Works fine for my regular vanity domain.

in asia it is frequent that email domain is a dropdown not a type in

Within the last month both Mapbox and Etsy blocked my attempts to signup using a Proton Mail alias. How many services do you sign up for in recent years, on average? The practice is becoming incredibly common and more than likely you're just grandfathered in.

		are you sure they're not just blacklisting protonmail vs. whitelisting known providers? ime a lot of sites block "temporary" or "anonymous" email providers

▲ BiteCode_dev 5 hours ago | parent | prev [-]

Yes, espacially exotic tld. I have a ".email" domain name, and I get 2 to 3 instances a year of either rejected forms, or sneakier, just confirmation email that never come until I use a .com address.

▲ threeio 4 hours ago | parent [-]

I have a 3 character .com as my primary email... it gets rejected more often than I'd like... including at my bank :) I've got a longer more normal domain that I alias, but it annoys me none the less.

		Have you got this lot sorted out: `MX->A->PTR->A->MX SPF DKIM DMARC mta-sts - DNS and webpage` Also your IPs must be squeaky bum clean, ideally for several years. DNSSEC might help too. In the UK getting as far as DKIM is usually enough (plus clean IPs, even FTTC connections will work if static).

I have never encountered one.

		Popular gaming forums NeoGaf and Resetera only allow signups from paid email accounts. All free and temporary email providers are banned to discourage trolls / forum raids / alt accounts.

		Ars Technica is one you can test I believe. I think I had to register with Gmail and put in a support ticket to ask them to change it to my real email. I use Fastmail, not a selfhosted setup or anything, some services absolutely have a domain allowlist for email signup.

▲ Hnrobert42 5 hours ago | parent | prev | next [-]

Nah. I have hosted my domain for 17 years on google and then fastmail. The hosting is harder than private relay, although not too hard.

But I have only had maybe 3 services ever reject my domain, and those were because the domain contains a number.

I've had some reject my e-mail address because it contains their company name. REI was one (ie it wouldn't allow rei@domain.com but would accept reicoop@domain.com)

▲

janc_ 21 minutes ago | parent | next [-]

Should have registered as rei-are-incompetent-idiots@ instead…

▲

js2 5 hours ago | parent | prev | next [-]

I was just able to create an account using `rei@<mydomain>` on rei.com w/o any issues. Now, figuring out how to delete the account is another matter entirely...

▲

snark42 4 hours ago | parent [-]

Cool, they probably changed it, this was years ago. I've had similar issues with other companies, REI is just the only one I can I really recall right now.

I haven't had an outright rejection, but definitely a few odd moments with call center agents. "theircompanyname@myname.com" is definitely not the default expectation :)

Within the space of 2 weeks I had both Etsy and Mapbox block signups with Proton Mail aliases. The practice is rapidly becoming more common.

Blocking signups from proton.me is not the same thing as only allowing signups from the big mail providers.

	▲	lukeify an hour ago \| parent [-]
		Great, so all I need to do is to authoritatively check each plausible combination of domains that _might_ work and rule each of them? What a load of pedantry.

▲ jbverschoor 3 hours ago | parent | prev | next [-]

Less private, but the most common case is actually anti-harassment.

Plenty of providers, but perhaps Apple needs to be forced to open up hide-my-email-providers for others.

Only the EU is capable of doing such thing

▲ bigstrat2003 3 hours ago | parent | prev | next [-]

I have had my own domain for mail for 10 years. I have yet to ever see a service which didn't let me sign up with it. I'm willing to believe that such services exist, but I dispute the claim that there are a lot of them.

▲ stavros 3 hours ago | parent | prev | next [-]

I've had my own domain for email for twenty years or so now, and I've encountered maybe one signup form that didn't accept it. What you're saying is definitely not true, and I would highly recommend using your own domain for email (preferably with Fastmail, it's fantastic).

I mean none of this is accurate, but sure.
