DATE Sent date and time from the Date: header, adjusted by time zone. This differs from the SENTON criteria in SEARCH, which uses just the date and not the time, nor adjusts by time zone. If the sent date can not be determined (a Date: header is missing or can not be parsed), the INTERNALDATE for that message is used as the sent date.
Very interesting... two different pages on the IETF's website have two different texts for version 19 of that draft. Odd.
Anyway, at best, it would seem that the text has multiple potential interpretations, because the parenthetical explanation there of what it means for a sent date to be un-determinable is different from (and contradictory of) what it says in section 2.2 (which is what I quoted).
I think you should bring these up in imap-protocol list. I noticed this only because I was comparing Dovecot's and UW-IMAP's SORT output and wondered why it was different.
