Moved to Posteo from Proton to save money and because of some of Andy Yen’s recent comments. I’ve been trying to find a workaround to sending with my custom domain, but so far no privacy-friend solutions have presented themselves. I like being able to use email clients like Thunderbird and FairEmail, but do I just need to suck it up and go back to Proton?
check out mailbox.org
This may be an unpopular mention by me but Fastmail (while not necessarily highly private as Tuta or Proton may be) is also a great option. Fantastic UI, apps, and feature set. But if you have a higher threat model or need better privacy, then Mailbox is a great option too.
Posteo doesn’t support custom domain natively but theres a few workaround:
1- for incoming you use either your registrar free email forwarding or you move dns to cloudflare and use cloudflare email routing, route to your posteo native address. Theres also forwardemail.net for that. For outgoing, posteo do support sending from their native address on behalf of address on your custom domain. Might need to add spf records to not have the on behalf outgoing mail be treated as spam since the on behalf thingy is technically spoofing. If you use thunderbird, for outgoing you use the built-in identity feature.
2- use simplelogin for both incoming and outgoing.
3- use addy.io for both incoming and outgoing.
All 3 is a bit hackish, would have either the incoming only for #1 and both incoming and outgoing for #2 and #3 being handled by outside third party, not posteo directly so there might be privacy and/or security issue there.
I’m using approach #3 and it works well enough for me. I do have to trust addy.io, but I could always self-host addy if needed.
Thanks for the recommendations all. After some research and consideration, I think I’ll go over to mailbox.org, for the simplicity of setup. It’s a modest price increase, but I can live with it.
