I was also thinking of protonmail, but :
- it requires clients other than IMAP/SMTP (there is a bridge available https://proton.me/mail/bridge )
- you need a paying plan for custom email domain https://proton.me/mail/pricing
@ancilevien74 @msgood531@mastodon.social I don't mind paying for service (I do that now anyhow). But the bridge was a problem for me, especially since I want to use my preferred clients on mobile. Also they seem to attract a lot of abuse, and there are accounts of people's legit accounts being deleted, and also of other servers refusing to accept mail from Proton.
