Thanks for the update Benny.

Re WKWebView, can the new features be selectively enabled? For example, I am locked (because some apps are locked to it) to MacOS 10.12 right now. Can image blocking be not enabled and MM still use WK except for that feature such that it will work in 19.12?

Re Gmail: good! If MM is forced to drop Gmail, I’ll finally drop all those horrible “free” accounts.

> WKWebView
> Right now I'd just like to note that I'm busy working on replacing the main message view in MailMate. It currently uses the so-called WebView class provided by Apple, but this was deprecated a long time ago (by Apple) and it should be replaced by a so-called WKWebView. Both classes are used to display HTML (which MailMate also generates to display plain text messages) and if that is all that is needed then it's a simple replacement. But MailMate also has image blocking, context sensitive menus, text search, etc. and all of this has to work in a completely different way. In some cases, it's not even clear that I can provide the same features as before. We'll see about that. WKWebView is 10.10+, but right now it looks like image blocking can only work on 10.13+. I'm not quite sure what to do about that yet...
> The latest test release includes the new message view, but it's disabled for now because too many things don't work yet. I'm mainly writing about this since some changes might also affect the old message view in the latest test release.
> The good news is that when the replacement is finished then I should, at least in theory, be able to fix various old issues.
> Google OAuth API Application Verification
> MailMate uses the so-called OAuth2 authentication method for Gmail IMAP/SMTP access. This works far better than password-based access which I suspect is eventually going to be dropped completely by Google. I had (and still have) some reservations about OAuth2 support which I outlined in this blog post. I expressed that I worried that Google would some day use OAuth2 to “hit the kill switch” on MailMate...
> ...and recently I was told by Google that I needed to start a verification process for MailMate. I've done that and if I understand correctly I have until the end of 2019 to complete this process.
> Now, the problem is that I'm not really sure I can (or is willing to) complete the verification process at all. It might include a security audit with a price tag between $15000 and $75000+ (I'm clearly in the wrong business). There seems to be exemptions for desktop email applications and I've asked Google to clarify this, but I also feel that I'm obligated to tell my users that I think it's a potential risk that MailMate cannot support Gmail starting January 1st, 2020. As soon as I fully understand what's going to happen, I'll make sure to clearly state it wherever it's relevant on the homepage and in the documentation.
