> First, I tried mailbox.org, which I can generally recommend without reservation. Unfortunately, you can’t send emails from any address on your own domain without a workaround

I use mailbox for a long time, one account for 2.50EUR/month with multiple custom domains and I can send emails from any address. To send from a different address the process didn't really seem different than other providers.

From Thunderbird mobile on Android I just add a new sender identity. If I need to send from webmail, similarly I just add a new alternative sender. Are these the workarounds you mentioned?

I use mailbox for the past few years and I think it's the best option out there. But they have one major issue, which is that anyone can impersonate your domain:

I wish they had retained one awesome Thunderbird desktop feature on mobile as well - being able to set the "from" address on the go while composing the email, without having to add an identity/sender-mail in advance. Alas, it seems that hasn't been the case.

    I don’t understand why this feature isn‘t more widespread, do people not use subaddressing?

Have been using mailbox.org with a custom domain (including catch-all wildcard) for the last 5 years or so, so it's definitely possible and as far I remember quite straightforward.

My understanding is that the number of such sender aliases is limited, at most 50 or 250, depending on the plan. There are ways to use a custom domain for sending where you end up using a larger number of localparts fairly quickly, and it would be a hassle to have to manage them, instead of just typing whatever sender you want (or on replies, having the email client automatically use the address from the original email, without having to worry whether it’s still in the set of registered aliases).

    The limit is only enforced in the web interface. You can send from any alias using any third party email client, and on the website you can configure a catchall mailbox and create a rule to filter out the aliases that receive spam.

    When you have a custom domain you can list @mydomain.com as sending domain allowing you every string before the at character. So that means you could use 50 different domains with infinite adresses on these domains.

...also migrating AWAY from Fastmail (Australian) and TO an European provider sounds like a very bad idea - I'd kind of want both the US and the EU legally away from my coms at all costs (!)
