heck, we still have WAY too many people using POP or IMAP with cleartext
passwords, mostly because that's the configuration that "works" with all
clients and servers, and partially because there's no uniform language to
describe the other configurations.  (does "use secure authentication" mean
APOP, or POP+SSL over a reserved port, or POP with the STARTTLS command?)

Usually none of the above :-) i.e. Microsoft proprietary authentication.

Of course MUAs should just use the protocol's negotiation features to
auto-configure the most secure settings possible. I get so annoyed that
they don't.


Are you referring to CAPA  Tony?

I guess you both right - Heck, by far I find sysops prefer to use POP BEFORE SMTP as the easiest - no instructions, less support required method to give their users instant auto-temporary-access to SMTP relay. :-) And thats a big item because its far easier than having to provide a link to variant MUA brand server login setup page.

In regards to the common MUA Server Account settings

    [X] Keep Mail on Server for _XX_ days

I always found this default setting to be sort of pompous on the side of MUA to assume they have real say on what servers do with received and unreceived mail storage. Nonetheless, if this 2822 Expire proposal moves on, I can only it see it being part of this common setup section. There would be two parts to consider:

a) Online storage where the server having unreceived messages with expire flags

    [X] Server MAY expire unreceived mail using RFC XXXX

 b) offline storage (picked up mail) which expires on the  MUA side.

    [X] Delete Expired Mail On Server

Also, I think this proposal will need to touch base with DKIM expiration tags as well.
