I don't know IMAP, but is there an IMAP server out there that will be
happy when I overwrite a hunk of ~/mail/inbox/42 in place? IMAP's a
textual protocol so we'd be switching one lot of text parsing in scan
for another. Would pick(1), when talking to `our' IMAP implementation,
make use of extensions to the protocol to save it effort, and fallback
if it's vanilla IMAP?
Good question!
In short:
- Messages in IMAP are immutable, so if you overwrite ~/mail/inbox/42, in
theory you should get a new UID for that message. But maybe our "internal"
IMAP implementation wouldn't care. I do wonder how UW-IMAP deals with
that, since it claims to be able to serve up MH folders via IMAP
- The grammar for IMAP is well-defined and pretty compact; I believe you'd
be able to minimize the client/server I/O. I don't think a parser would
be terrible for it.
- AFAICT, pick(1) is implementable completely via the "vanilla" IMAP
protocol, but if I'm wrong I'd be interested in knowing about it.
