Changes in version 0.9
Added Tunnel directive to allow the user to specify a shell command to run
to set up an IMAP connection in place of a TCP socket (eg., to run over
an SSH session).
Added PREAUTH support (useful mostly in conjunction with Tunnel).
Messages marked deleted are not uploaded when we are going to expunge.
Locally generated messages are not re-fetched after uploading even if the
UIDPLUS extension is not supported by the server.
Added `OneToOne' configuration option: ignore any Mailbox specifications
and instead pick up all mailboxes from the local MailDir and remote Folder
and map them 1:1 onto each other according to their names.
-C now creates both local and remote boxes; -L and -R create only local/remote.
--quiet is now really quiet.
mail/isync.
isync is a command line utility for synchronizing a remote IMAP mailbox
with a local maildir-style mailbox. This is useful for working in
disconnected mode, such as on a laptop. Modifications made locally and
remotely are synchronized so that no message status flags are lost.
