Hi all,

We're looking to get off Rackspace's email as the Spam filtering is pure garbage. We're going to avoid the Googles and MS's of the world, and I'm wondering if this community has suggestions for mail providers that run FOSS services (and are public about that via support), and/or are privacy focused. Note: Proton is a no-go due to having to run an IMAP middle-man service.

Thanks!

Mailbox.org is another candidate worth looking into.

They are very generous with aliases too: 25 mailbox aliases, 50 custom domain aliases. Compare to Proton, which allows only 10 non-revocable aliases for their domains and custom domains combined.

This is on my eval list, though I'm thinking Runbox is above it due to the unlimited aliases/etc. I also like their sub-account pricing structure.

Check Posteo. Working great for me since I left gmail.

[–] stame@lemmy.world 5 points 1 week ago (1 children)

Posteo is also my choice. It's now not only my main E-Mail adress, but also my sync for calendar and adressbook. When i decided not to use Google any more several years ago i considered hosting my own server or use a service. I ended up with Posteo and so far never regret it. Paying 1€/month is a better deal for me than maintaining my own server, as they use their own server which are located in Germany and seem to be really trustworthy.

Another quite similar service in Germany would be mail.de

Never heard of them. But their website says "try ad-free". That implies that they display ads after the trial!? If that's the case, they can't be trusted.

[–] stame@lemmy.world 1 points 1 week ago

No, they want to emphasize that the trial is ad free. After the trial you need to pay, but it's still ad free

Ahh I like a lot about this one, it's going into the list, though I think Runbox might be just above it.

Norwegian, privacy, ethical focus.

https://runbox.com/blog/2018/12/runbox-7-is-going-open-source/

Open source software powers most of the Internet, and makes up a large part of the platform Runbox is running on. Now Runbox 7 will become part of this global collaboration, and you can join in by visiting the Runbox repository on Github: https://github.com/runbox.

Not sure how much of their stack is open source but they work with providers who also specialise in open source (see 'Partners'):

This is spot on, and the top of my list now. Thanks!

Any provider which provides IMAP and SMTP over TLS is good. If you want privacy, you have to use E2EE through a mail software which supports it. However, I personally use riseup.net(Don't ask me for an invite code!)

As a bonus, there is also DeltaChat which provides E2EE email in a nice chat interface. https://delta.chat/ It also supports mini apps through https://webxdc.org/

Proton is a fascist-sympathizing walled garden and Tuta is a walled garden.

Mailbox.org is the best!

Hmm, is something going on with their site? I'm unable to load this.

[–] dragospirvu75@lemmy.ml 0 points 1 week ago (1 children)

Sometimes it doesn't work, maybe it's overloaded. Try again later!

[–] Fmstrat@lemmy.world 2 points 1 week ago

Ahh yea works now, and the suggestions mostly align to what's here, perfect. Thanks!
