f{,data}sync() usage could be optimized by batching the calls.
|
|
|
|
make SSL (connect) timeouts produce a bit more than "Unidentified socket error".
|
|
|
|
automatically resume upon transient errors, e.g. "connection reset by peer"
|
|
or timeout after some data was already transmitted.
|
|
possibly also try to handle Exchange's "glitches" somehow.
|
|
|
|
add support for IMAP UTF-7 (for internationalized mailbox names).
|
|
|
|
uidvalidity lock timeout handling would be a good idea.
|
|
|
|
should complain when multiple Channels match the same folders.
|
|
|
|
propagate folder deletions even when the folders are non-empty.
|
|
- verify that "most" of the folders in the Channel are still there.
|
|
- refuse to delete unpropagated messages when trashing on the remote side.
|
|
- refuse to delete master if it has unpropagated messages. symmetry?
|
|
|
|
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).
|
|
|
|
add support for event notification callbacks.
|
|
it would be also possible to report more differentiated exit codes, but
|
|
that seems too limiting in the general case.
|
|
|
|
make it possible to have different mailbox names for Master and Slave in
|
|
Patterns.
|
|
- use master:slave for the pattern
|
|
- for quoting, use more colons: the longest sequence of colons is the
|
|
separator
|
|
- this makes Groups mostly useless, as they are mostly a workaround for this
|
|
function being missing so far
|
|
- this is needed for move detection, which would work only within one Channel
|
|
|
|
normalize INBOX capitalization received from IMAP, to avoid anomalies.
|
|
|
|
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.
|
|
TLS session resumption becomes interesting then as well.
|
|
|
|
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.
|
|
|
|
some error messages are unhelpful in non-verbose mode due to missing context.
|
|
|
|
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 loss of sync state, migration from other tools
