Email service that integrates well with Thunderbird?
I hope I'm not annoying you kind folks too much with my ongoing Tutamail woes, but, in the long slow process of divorcing myself from them (and returning to Thunderbird), I'm looking for an email host/provider that integrates well with TB, meaning that it can sync mail, contacts, calendars, and tasks between the Linux desktop and Android. I've looked at so many different services, and each one seems to be missing one or more pieces of the puzzle. I've tried and did not like, for one reason or another, ProtonMail, Posteo, and Kolab (I can't necessarily remember the exact reason for not liking each). I've gone through alternativeto as well without much success; I am in the process of investigating Mailfence, which looks promising, but seems to lack a few things as well. I don't think I have the time or the brainpower to host my own email server either.
Looking over what I've just written, it seems like I've managed to make this a fairly challenging question, but I thought I should at least mention what I've already tried. Probably being too picky for my own good, but now that we're 10+ years out from The Snowden Affair, having a FOSS email service that does all these things seems like it should be kind of a no-brainer. Anyway, any and all suggestions are welcome, and apologies for the written filibuster.
P.S. The comments to this article would seem to suggest that a @thunderbird.com email is being considered, after K9 mail becomes TB Mail for Android, but who knows how far off that will be?
Ok, now pardon me while I go take another look at ProtonMail...
I use posteo.de and sync between Thunderbird on Linux, Thunderbird on OS X, Apple Mail on Desktop and iOS without problems. Calendar and contacts, too. My partner syncs between iPhone and Thunderbird on Windows.
The service is a German privacy aware mail service. It is 1€/Month.
Edit: didn’t see that you ruled out Posteo already. I still think it’s a great mail service.
Mailbox.org is nice and has calendar which works with TB. They also have tons of aliases in the 3€/mo plan, temporary addresses, enforced TLS encryption domain etc.
It's only the mobile apps of the auxillary services (drive, pass etc.) that are proprietary. And I don't get why either because it wouldn't hurt them one bit.
I use mailfence. They offer imap, caldav, and carddav. It'll check all those boxes, but I don't think those are unique offerings among the privacy respecting email services.
I use Proton Mail's Proton Calendar app for my calendar though. I was using caldav + davx5 but I had issues with reminder settings getting lost on recurring events.
So any web host that uses cPanel should be a good thing. IMAP for mail, Caldav for Calendars and Cardav for contacts. It's what I use anyway and haven't had any issues
No, cPanel is the interface you use to manage your hosting package. It's the Admin part to add & remove domains, websites, email, etc.
In cPanel you can set up your email for your personal domain(s).
Roundcube is a web email client that can be used to access your email. Or you can use a client like Thunderbird on your device.
Pretty much any IMAP mail provider combined with Nextcloud for sync will work.
Keep in mind too that Proton Mail has a commercial offering that should work with thunderbird. I have no experience with it.
We use our ISPs mail with our Nextcloud instance but long run will probably move to domain mail with maybe Fastmail for the mail component. Not sure yet. I will be interested in what you find.
