|
f{,data}sync() usage could be optimized by batching the calls.
|
|
|
|
|
|
|
|
|
|
add some marker about message being already [remotely] trashed.
|
|
|
|
|
real transactions would be certainly not particularly useful ...
|
|
|
|
|
|
|
|
|
|
make sync_chans() aware of servers, so a bad server (e.g., wrong password)
|
|
|
|
|
won't cause the same error message for every attached store.
|
|
|
|
|
|
|
|
|
|
make SSL (connect) timeouts produce a bit more than "Unidentified socket error".
|
|
|
|
|
|
|
|
|
|
network timeout handling in general would be a good idea.
|
|
|
|
|
lock timeout handling, too.
|
|
|
|
|
|
|
|
|
|
add message expiration based on arrival date (message date would be too
|
|
|
|
|
unreliable). MaxAge; probably mutually exclusive to MaxMessages.
|
|
|
|
|
|
|
|
|
|
add alternative treatments of expired messages. ExpiredMessageMode: Prune
|
|
|
|
|
(delete messages like now), Keep (just don't sync) and Archive (move to
|
|
|
|
|
separate folder - ArchiveSuffix, default .archive).
|
|
|
|
|
|
|
|
|
|
kill the concept of an INBOX, it is a relic from single-channel operation.
|
|
|
|
|
if somebody needs it, he can have two stores with different Paths. the path
|
|
|
|
|
can name a single (in-)box (curr. broken with maildir). an empty box name
|
|
|
|
|
actually means empty, so the IMAP mailbox should use INBOX for Path (can't
|
|
|
|
|
make that the default, as it would mess up the NAMESPACE).
|
|
|
|
|
|
|
|
|
|
add regexp-based mailbox path rewriting to the drivers. user would provide
|
|
|
|
|
expressions for both directions. every transformation would be immediately
|
|
|
|
|
verified with the inverse transform. PathDelimiter and Flatten would become
|
|
|
|
|
special cases of this.
|
|
|
|
|
|
|
|
|
|
add daemon mode. primary goal: keep imap password in memory.
|
|
|
|
|
also: idling mode.
|
|
|
|
|
|
|
|
|
|
parallel fetching of multiple mailboxes.
|
|
|
|
|
|
|
|
|
|
imap_set_flags(): group commands for efficiency, don't call back until
|
|
|
|
|
imap_commit().
|
|
|
|
|
|
|
|
|
|
add streaming from fetching to storing.
|
|
|
|
|
|
|
|
|
|
handle custom flags (keywords).
|
|
|
|
|
|
|
|
|
|
make use of IMAP CONDSTORE extension (rfc4551; CHANGEDSINCE FETCH Modifier);
|
|
|
|
|
make use of IMAP QRESYNC extension (rfc5162) to avoid SEARCH to find vanished
|
|
|
|
|
messages.
|
|
|
|
|
|
|
|
|
|
use MULTIAPPEND and FETCH with multiple messages.
|
|
|
|
|
|
|
|
|
|
create dummies describing MIME structure of messages bigger than MaxSize.
|
|
|
|
|
flagging the dummy would fetch the real message. possibly remove --renew.
|
|
|
|
|
note that all interaction needs to happen on the slave side probably.
|
|
|
|
|
|
|
|
|
|
don't SELECT boxes unless really needed; in particular not for appending,
|
|
|
|
|
and in write-only mode not before changes are made.
|
|
|
|
|
problem: UIDVALIDITY change detection is delayed, significantly complicating
|
|
|
|
|
matters.
|
|
|
|
|
|
|
|
|
|
possibly use ^[[1m to highlight error messages.
|
|
|
|
|
|
|
|
|
|
consider alternative approach to trashing: instead of the current trash-before-
|
|
|
|
|
expunge done by mbsync, let MUAs do the trashing (as modern ones typically do).
|
|
|
|
|
mbsync wouldn't do any trashing by itself, but should track the moves for
|
|
|
|
|
optimization. additionally, there should be a mode to move trashed messages to
|
|
|
|
|
the remote store. TrashMode Internal|External, AbsorbRemoteTrash.
|
|
|
|
|
a yet different approach to trashing is treating the trash like a normal mailbox.
|
|
|
|
|
however, this implies a huge working set.
|
|
|
|
|
|
|
|
|
|
consider optional use of messages-id (and X-GM-MSGID):
|
|
|
|
|
- detection of message moves between folders
|
|
|
|
|
- recovery from unmotivated UIDVALIDITY change, or total loss of sync state
|
