Regarding date formats, I wonder if many/most IMAP servers support the unambiguous ISO 8601 date format? (http://en.wikipedia.org/wiki/ISO_8601) To my mind, anyone creating software that has even a remote possibility of having to deal with multiple formats (and I’d say IMAP server software qualifies!) should always support ISO 8601 and use it internally… Sadly, though, to the extent it’s even covered by the RFC (http://www.faqs.org/rfcs/rfc3501.html) — and why do we keep making the mistake of not defining these things?! — it looks like they’ve done exactly the wrong thing and require DD-MM-YYYY (at least, that’s how it looks to me in the Formal Syntax section, but I’m not an expert at ABNF)…
