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.

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

Mailbox.org is decent as well

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 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.

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 like and trust Proton Mail, and they support setting up custom domains while hosting your email data (for subscriber users).

You can then access it via their web mail box, via their Android and iOS apps, or via a desktop email client if you install their “bridge” application. The bridge application basically maintains the secure encryption ethos of their email system by ensuring all email traffic between your desktop and their servers remains encrypted, but can still be accessed via your preferred email clients such as Thunderbird or Outlook. The bridge is available for Windows, iOS and Linux.

I personally recommend Protonmail as it’s primary focus is security and encryption, yet it does this in a very well developed and slick interface, so you get the best of both worlds. I’m a subscriber and moved from Gmail about 2 years ago as I wanted better privacy and security (they even have great tools for importing your old emails from major web providers). I don’t have a custom domain but from my experiences of everything else they provide, I’d be confident it works as intended.

EDIT: In terms of cost, its €4 a month for the first tier which includes support for 1 custom domain, 10 email addresses, and 15GB of storage, or €10 for 500GB, 3 domains, 15 emails. They also include VPN, calendar, drive storage and a password manager in both.

Proton mail offers catchall, assuming you mean what I think you do. Basically I can receive mail sent to [email protected], though my account only has 5 named accounts that I can send from.

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

I’ve been using Tutanota. They are kind of similar in principles to Protonmail, but until recently were dirt cheap at €12/yr (now €36/yr). The only “drawback” is that you can only access your mail through their app, this is a feature, not a bug, according to Tutao.

I’ve been very happy with mxroute for quite a few years now. They have a summer deal going on for $40 a year for unlimited domains and accounts, you’re only limited by storage (100GB) and outgoing emails per hour.
t would be helpful to know what you consider basic features you want the host to support, but catchall works.

I’ve just moved my email hosting from Fastmail to Migadu, very competitive pricing if you have a lot of users/mailboxes/domains but not that much email traffic

Not self-hosted, however Proton supports custom domains and catch-all. Their monthly plans are very reasonable IMO.
