Since this is related to moving out of Yahoo, in a previous thread about the security breach at Yahoo, I had asked for suggestions on other email providers who're better focused on privacy, security (and related to that, freedom). I came across a few suggestions that support custom domains, but found all of them wanting in some ways:<p>1. Fastmail - becomes very expensive if multiple people (say, in a team or family) want individual accounts even if their actual usage volumes are less. Pricing by user account is the barrier here, instead of pricing by usage (consider that it provides 600 aliases per user, which 99% of users wouldn't use to the full extent, but charges based on user accounts). Provides support for IMAP/POP, importing existing mails from other accounts and exporting mails out. A few hundred dollars a year for email is quite expensive for me.<p>2. Protonmail - no way to import mails from existing mail accounts or to export mails from the system. The lack of support for IMAP/POP means one does not have the freedom to move out. Suggestions on these have been waiting for two years with nothing to show for. Pricing is somewhat similar to Fastmail, but offers more flexibility. This too could get very expensive even with lower actual usage per user.<p>3. Tutanota - much better on flexible pricing based on different parameters, but it's similar to Protonmail in that it does not support importing existing mail or exporting mails out. It too lacks support for IMAP/POP and states that it's never going to support them for privacy reasons.<p>4. Startmail - quite similar to Fastmail on the pricing issue, but has IMAP support.<p>Are there any other providers who do better on all these fronts? I'd like to use custom domains, have multiple user accounts (with separate credentials), preferably manage storage across users, be able to import and export mails, and have IMAP/POP support in order to use different systems (phones, tablets, computers with different operating systems). I don't believe that web mail and custom apps ought to be the only way to use email.
