I have actually wished for someone to create an open-source self-hostable copycat of Gmail (the UI) for a long time. Having trialled a multitude of alternatives (both commercial and open-source) I haven't found anything that doesn't require a huge adjustment re: usability and many compromises feature-wise.
Unfortunately, both in design and feature philosophy, Gmail is and has been for years the "non plus ultra" imho (and I gladly left Outlook-style emailing behind for it).
Of course it too still has room for improvements but they will probably never happen (such as a one-touch PGP integration or better usability with many aliases), as we have most likely already reached "peak-Gmail". (Many other services, incl. Google Search, have also been deteriorated slowly, de facto killed (Google Books) or "optimised" to fit Google's/Alphabet's new strategy).
As a user of pretty much the first hour (when it was still invite only) and having moved several companies over to Gsuite from Exchange, I've felt more and more queasy over the last months and years...
When I found out recently thanks to a HN post that even my highest-paid Gsuite accounts track ALL my purchases (and many that aren't actually mine) and this CANNOT be switched off or deleted, it sort of finally broke the part of my heart that kind of still hung on to the old and long-since gone spirit of "don't be evil"...
Sorry for the rambling.
Bottom line: I do not know if you have any plans to add a "Gmail"-type email client/front-end (which could easily utilise one of the many very good open source email servers and spam filters) but I for one would welcome it with open arms.
Mails are currently not a priority because it's really hard to make it right (IMAP, POP and all the things...), but if the community shows an interest, we may plan it :)
Literally, it means "not more further", i.e. it is the peak, there is nothing better, this is the ultimate thing compared to others (like, you could say "my Model X is the non plus ultra of electric SUVs", just for example).
I guess it is not a common expression but I like the phrase. ;-)
