Imapsync command is a tool allowing incremental and

You can decide to delete the messages from the source mailbox
after a successful transfer, it can be a good feature when migrating
live mailboxes since messages will be only on one side.
.PP
In that case, use the \-\-delete1 option. Option \-\-delete1 implies
also option \-\-expunge1 so all messages marked deleted on host1
will be really deleted.
.PP
You can also decide to remove empty folders once all of their
messages have been transferred. Add \-\-delete1emptyfolders to
obtain this behavior.

A classical scenario is synchronizing a mailbox B from another mailbox A
in case you just want to keep a strict copy of A in B. Strict meaning
all messages in A will be in B but no more.
.PP
For this, option \-\-delete2 has to be used, it deletes messages in host2
folder B that are not in host1 folder A. If you also need to destroy
host2 folders that are not in host1 then use \-\-delete2folders. See also

.PP
A different scenario is to delete the messages from the source mailbox
after a successful transfer, it can be a good feature when migrating
mailboxes since messages will be only on one side. The source account
will only have messages that are not on the destination yet, ie,
messages that arrived after a sync or that failed to be copied.
.PP
In that case, use the \-\-delete1 option. Option \-\-delete1 implies also
option \-\-expunge1 so all messages marked deleted on host1 will be really
deleted. In \s-1IMAP\s0 protocol deleting a message does not really delete it,
it marks it with the flag \eDeleted, allowing an undelete. Expunging
a folder removes, definitively, all the messages marked as \eDeleted
in this folder.

.IX Header "HISTORY"
I wrote imapsync because an enterprise (basystemes) paid me to install
a new imap server without losing huge old mailboxes located in a far
away remote imap server, accessible by a low-bandwidth often broken link.
The tool imapcp (written in python) could not help me because I had to verify
every mailbox was well transferred, and then delete it after a good
transfer. Imapsync started its life as a patch of the copy_folder.pl
I initially wrote imapsync in July 2001 because an enterprise,
basystemes, paid me to install a new imap server

away remote imap server, accessible by an
often broken low-bandwidth \s-1ISDN\s0 link.

I had to verify every mailbox was well transferred, all folders, all messages,
without wasting bandwidth or creating duplicates upon resyncs. The design was
made with the beautiful rsync command in mind.

Imapsync started its life as a patch of the copy_folder.pl
script. The script copy_folder.pl comes from the Mail\-IMAPClient\-2.1.3 perl
module tarball source (more precisely in the examples/ directory of the
Mail-IMAPClient tarball). So many happened since then that I wonder
if it remains any lines of the original copy_folder.pl in imapsync source code.
