I used bridge for many years. It was totally unusable - 1) you cannot delete emails with it ( deleted emails were coming back ), 2) synchronization issues so it made me move to another “plain and simple” email provider offering pop3 and imap and also gpg integration ( but without that e2e hype talk )
I can’t comment on this, since I don’t use the bridge for a while. But it’s just an IMAP/SMTP server, so not sure why certain features wouldn’t work. What service did you end up using which has gpg integration?
I used protonmail for 3 years - bridge issues have been being ignored by protonmail support in my opinion. “Clean cache and try again”. I stopped using protonmail and switched to mailbox.org. So far so good.
From what I read though, the GPG security model for mailbox.org is the same as it is for Proton webmail (except for the browser plugin, where the difference is not really there). I like mailbox.org, to be clear, but I don’t get how it is an alternative to the bridge.
