I can’t recommend Migadu enough. I’m on the $99/year plan and have dozens of domains and clients with their own domains too, it’s easy to manage and does everything I need it to.

I use Proton mail and Anonaddy.

Honestly any service that offers cPanel can allow mail hosting and a catchall.

If you just want a basic IMAP/SMTP service with nothing fancy I know these guys do allow catch all mailboxes https://hostinguk.net/email

If it is just for email forwarding maybe a service like https://anonaddy.com/ or https://simplelogin.io would work. Catch-all is even included in the anonaddy free plan as that is something you actually do not want to have enabled 😄 For your custom domain you have to have the lite plan at least though.

For 24$/year porkbun has been really easy!

What about Microsoft 365? The tenant itself is free and per account and month you pay about 5-10$ (depending on sibscription level).

With this you have the full MS Exchange experience, you get 1TB of OneDrive space and all the shebang.

I use Fastmail and it’s pretty reasonable, has some nice tie-ins with 1Password, alias emails, etc.

Funny 😄 pretty much asked myself the same thing, the day before yesterday.

Specifically, I have been looking for encrypted mail hosters supporting your own domain. Also, hosting in Europe on dedicated Hardware (or at least guaranteed European VPS), GDPR compliance and some sort of certification/ verification of the said requirements and their claims!

What I came up with:

• mailbox.org (never heard of it before, but pretty much has your requirements covered) <- Tor nodes, anonymous accounts(no personal data at all!)
• proton mail
• Tutanota (pretty young - but interesting concept)

I won’t cite their individual plans - that’s for you to figure out in detail.

The thing that bugs me with the Proton Mail and Tutanota, to effectively make use of their threat model/ encryption you have to use their Apps/ Software. EDIT: I’m currently using Microsoft365 - with it you are pretty much locked in - I fear with Proton or Tutanota it’s the same. Migrating is a pain.

I’m trying mailbox.org at the moment - they got a 30-free trail.

Check out PurelyMail. It’s $10 a year, unlimited custom domains, unlimited emails, privacy focused.

Side question. Does anybody know of a decent service that basically works as a smarthost for outgoing and will MX incoming emails back to a mail server I host? I’ve been self hosting email since the '90s and just don’t want all of my email stored elsewhere. The IP reputation chasing is just too much to deal with now.

I have a couple domains that are very low volume for outgoing mail. I use Migadu. I’m happy with their cheapest tier ($19/year for both domains). They have catch-alls and many other nice features.

Edit: They have no hard limits on the number of addresses, users, or domains and such. They just want you to be reasonable. You choose a tier based on your average quantity of outgoing mails per day. Again, there are no hard limits; they won’t cut you off unless you abuse the system.

Whatever hosting service you’re going to use, if you’re not afraid of a little bit of Lua coding, consider using imapfilter – it’s a swiss knife for backups, pre-sorting, hooks and migration.

imapfilter is a (criminally underrated, IMO) tool for writing e-mail rules in Lua, which allow you to do tons of things, but my favorite is migrating e-mail, regardless of account.

See, unlike most filtering/sorting systems which are either completely proprietary or limited to single account (exportable as Sieve, if you’re lucky), imapfilter does not care where each “end” of the rule is: you can write rule that migrates from account1/folder1 to account2/folder3.

This allows you to completely decouple any sorting, pre-processing, hook or backup system from the actual locations or providers you happen to be using, as well as it allows you to combine any number of locations in any simple or complex way you need. Whatever system you will end up creating will stay with you as long (as you can use IMAP locations), so you can really focus on making it work long-term and have it fit into the big picture.

I’ve been using it for almost 10 years and ever since it has changed my whole world of e-mail. I have constant set of rules that take e-mails from set of inboxes (each box for different purpose, each on different provider, for reasons) and sort them to folders on my “actual” account, where I get to read them on my terms. I also have several of rules that run custom scripts exporting CSV’s, etc. (The rules are Lua programs, after all, so sky is the limit.) If I ever need to migrate my domain to another service (believe it or not, happened more than once in 10 years), all I need to do is set up the new account as base for the rules, but all of my rules are always going to be preserved.

In my past work I actually used imapfilter to move all IMAP from company Gmail to a locally maintained (on company laptop) Dovecot instance so that I could eventually use a sane client to get my work done. (And because the instance was local, I could access my e-mail offline with best possible speed.) One could do a similar thing with personal/freelance e-mail – just run Dovecot somewhere at a trusted place (you won’t be sending/receiving e-mails here, you will be only using IMAP to IMAP commands, so none of the horrors of self-hosting e-mail apply) and use imapfilter to route all email there, then back up your dovecot folder and you’re all set.

Except for need of coding, the disadvantage is that, I need an independent machine that runs 24/7 in order to keep sorting the e-mail (I do it cron-based but you can also do it continually) but that has not been a problem for me as I’m the self-hosting-nerd that’s going to have such machine anyway.

I use free tier of Zoho Mail and it works well enough for me. Need to use their app though but it’s not too bad (the cheapest tier has imap iirc)

I self host my imap Server that my clients access. I have a minutely cron job that first fetches, then deletes, the emails from my mail provider.

I don’t self host smtp.

With that I have all the advantages of self hosted email, but no integration problems.
