imapsync \- Email IMAP tool for syncing, copying and migrating

and without duplicates.

.SH "USAGE"
.IX Header "USAGE"
.Vb 5
\& To synchronize the source imap account
\& "test1" on server "test1.lamiral.info" with password "secret1"
\& to the destination imap account
\& "test2" on server "test2.lamiral.info" with password "secret2"

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
We sometimes need to transfer mailboxes from one imap server to
one another.
.PP
Imapsync command is a tool allowing incremental and
recursive imap transfers from one mailbox to another.
.PP
By default all folders are transferred, recursively, meaning
the whole folder hierarchy is taken, all messages in them,
and all messages flags (\eSeen \eAnswered \eFlagged etc.)
are synced too.
.PP
Imapsync reduces the amount of data transferred by not transferring
a given message if it resides already on both sides.
.PP
Same specific headers and the transfer is done only once.
By default, the identification headers are
\&\*(L"Message-Id:\*(R" and \*(L"Received:\*(R" lines
but this choice can be changed with the \-\-useheader option.
.PP
All flags are preserved, unread messages will stay unread,
read ones will stay read, deleted will stay deleted.
.PP
You can stop the transfer at any time and restart it later,
imapsync works well with bad connections and interruptions,
by design.
.PP
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.
.PP
A different scenario is synchronizing a mailbox B from another mailbox A
in case you just want to keep a \*(L"live\*(R" copy of A in B.
.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
\&\-\-delete2foldersonly and \-\-delete2foldersbutnot.
.PP
Imapsync is not adequate for maintaining two active imap accounts
in synchronization when the user plays independently on both sides.
Use offlineimap (written by John Goerzen) or mbsync (written by
Michael R. Elkins) for a 2 ways synchronization.
.SH "OPTIONS"
.IX Header "OPTIONS"
.Vb 1
\& usage: imapsync [options]
.Ve
.PP
Mandatory options are the six values, three on each sides,
needed to log in into the \s-1IMAP\s0 servers, ie,
a host, a username, and a password, two times.
.PP
Conventions used:
.PP
.Vb 4
\& str means string
\& int means integer
\& reg means regular expression
\& cmd means command
\&
\& \-\-dry : Makes imapsync doing nothing for real, just print what
\& would be done without \-\-dry.

\& \-\-host1 str : Source or "from" imap server. Mandatory.

You can use \-\-passfile1 instead of \-\-password1 to give the
password since it is safer. With \-\-password1 option, any user
on your host can see the password by using the 'ps auxwwww'
command. Using a variable (like \f(CW$PASSWORD1\fR) is also
dangerous because of the 'ps auxwwwwe' command. So, saving
the password in a well protected file (600 or rw\-\-\-\-\-\-\-) is
the best solution.

Imapsync activates ssl or tls encryption by default, if possible.
What detailed behavior is under this \*(L"if possible\*(R"?
Imapsync activates ssl if the well known port imaps port (993) is open
on the imap servers. If the imaps port is closed then it open a
normal (clear) connection on port 143 but it looks for \s-1TLS\s0 support
in the \s-1CAPABILITY\s0 list of the servers. If \s-1TLS\s0 is supported
then imapsync goes to encryption.
.PP
If the automatic ssl/tls detection fails then imapsync will
not protect against sniffing activities on the
network, especially for passwords.
.PP
If you want to force ssl or tls just use \-\-ssl1 \-\-ssl2 or \-\-tls1 \-\-tls2

shell program. Write a file called file.txt (for example)
containing users and passwords.
The separator used in this example is ';'

.SH "HISTORY"
.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
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.
