=head1 NAME
imapsync - IMAP synchronisation, sync, copy or migration
tool. Synchronise mailboxes between two imap servers. Good
at IMAP migration. More than 32 different IMAP server softwares
supported with success.
$Revision: 1.213 $
=head1 INSTALL
imapsync works fine under any Unix OS with perl.
imapsync works fine under Windows 2000 (at least) and ActiveState's 5.8 Perl
imapsync is already available on the following distributions (at least):
FreeBSD, Debian, Gentoo, NetBSD.
Get imapsync at
http://www.linux-france.org/prj/imapsync/dist/
You'll find a compressed tarball called imapsync-x.xx.tgz
where x.xx is the version number. Untar the tarball where
you want :
tar xzvf imapsync-x.xx.tgz
Go into the directory imapsync-x.xx and read the INSTALL
file.

=head1 DESCRIPTION
The command imapsync is a tool allowing incremental and recursive
imap transfer from one mailbox to another.
We sometimes need to transfer mailboxes from one imap server to
another. This is called migration.
imapsync is the adequate tool because it reduces the amount
of data transferred by not transferring a given message if it
is already on both sides. Same headers, same message size
and the transfer is done only once. All flags are
preserved, unread will stay unread, read will stay read,
deleted will stay deleted. You can stop the transfer at any
time and restart it later, imapsync is adapted to a bad
connection. imapsync is CPU hungry so nice and renice
commands can be a good help. imapsync can be memory hungry too,
especially with large messages.
You can decide to delete the messages from the source mailbox
after a successful transfer (it is a good feature when migrating).
In that case, use the --delete --expunge1 options.
You can also just synchronize a mailbox A from another mailbox B
in case you just want to keep a "live" copy of B in A.
=head1 OPTIONS
Invoke: imapsync --help
=head1 HISTORY
I wrote imapsync because an enterprise (basystemes) paid me to install
a new imap server without loosing huge old mailboxes located on a far
away remote imap server accessible by a low bandwith link. The tool
imapcp (written in python) could not help me because I had to verify
every mailbox was well transferred and delete it after a good
transfer. imapsync started its life being a copy_folder.pl patch.
The tool copy_folder.pl comes from the Mail-IMAPClient-2.1.3 perl
module tarball source (in the examples/ directory of the tarball).
=head1 EXAMPLE
While working on imapsync parameters please run imapsync in
dry mode (no modification induced) with the --dry
option. Nothing bad can be done this way.
To synchronize the imap account "buddy" on host
"imap.src.fr" to the imap account "max" on host
"imap.dest.fr" (the passwords are located in two files
"/etc/secret1" for "buddy", "/etc/secret2" for "max") :
imapsync --host1 imap.src.fr --user1 buddy --passfile1 /etc/secret1 \
--host2 imap.dest.fr --user2 max --passfile2 /etc/secret2
Then, you will have buddy's mailbox updated from max's
mailbox.
=head1 SECURITY
You can use --password1 instead of --passfile1 to give the
password but it is dangerous because any user on your host
can see the password by using the 'ps auxwwww'
command. Using a variable (like $PASSWORD1) 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.
imasync is not totally protected against sniffers on the
network since passwords may be transferred in plain text in
case CRAM-MD5 is not supported by your imap servers. Use
--ssl1 and --ssl2 to enable encryption on host1 and host2.
You may authenticate as one user (typically an admin user),
but be authorized as someone else, which means you don't
need to know every user's personal password. Specify
--authuser1 "adminuser" to enable this on host1. In this
case, --authmech1 PLAIN will be used, but otherwise,
--authmech1 CRAM-MD5 is the default. Same behavior with the
--authuser2 option.
=head1 EXIT STATUS
imapsync will exit with a 0 status (return code) if everything went good.
Otherwise, it exits with a non-zero status.
So if you have a buggy internet connection, you can use this loop
in a Bourne shell:
while ! imapsync ...; do
echo imapsync not complete
done

Feedback good or bad is always welcome.
The newsgroup comp.mail.imap is a good place to talk about
imapsync. I read it when imapsync is concerned.

=head1 BUGS
No known serious bug. Report any bug to the author.
Before reporting bugs, read the FAQ, this README and the
TODO files.
In your report, please include:
- imapsync version.
- IMAPClient.pm version.
- perl version.
- operating system running imapsync.
- imap servers softwares on both side and their version.
Those values can be found with the command line
imapsync --host1 imap.host1.net --host2 imap.host2.org --justconnect
And also, if it can help :
- operating systems on both sides and the third side in case
you run imapsync on a foreign host from the both.
- imapsync with all the options you use, the full command line
you use (except the passwords of course). This can be found
at the beginning of the output.
- output given with --debug --debugimap near the failure point.
=head1 IMAP SERVERS

=head1 HUGE MIGRATION
Have a special attention on options
--subscribed
--subscribe
--delete
--delete2
--expunge
--expunge1
--expunge2
--maxage
--minage
--maxsize
--useheader
If you have many mailboxes to migrate think about a little
shell program. Write a file called file.csv (for example)
containing users and passwords.
The separator used in this example is ';'
The file.csv file content is :
user0001;password0001;user0002;password0002
user0011;password0011;user0012;password0012
...
And the shell program is just :
{ while IFS=';' read u1 p1 u2 p2; do
imapsync --user1 "$u1" --password1 "$p1" --user2 "$u2" --password2 "$p2" ...
done ; } < file.csv
Welcome in shell programming !

--password1 <string> : password for the user1. Dangerous, use --passfile1
--passfile1 <string> : password file for the user1. Contains the password.
--host2 <string> : "destination" imap server. Mandatory.
--port2 <int> : port to connect on host2. Default is 143.
--user2 <string> : user to login on host2. Mandatory.
--authuser2 <string> : user to auth with on host2 (admin user).
--password2 <string> : password for the user2. Dangerous, use --passfile2
--passfile2 <string> : password file for the user2. Contains the password.
--noauthmd5 : don't use MD5 authentification.
--authmech1 <string> : auth mechanism to use with host1:
PLAIN, LOGIN, CRAM-MD5 etc.
--authmech2 <string> : auth mechanism to use with host2. See --authmech1
--ssl1 : use an SSL connection on host1.
--ssl2 : use an SSL connection on host2.
--folder <string> : sync this folder.
--folder <string> : and this one, etc.
--folderrec <string> : sync this folder recursively.
--folderrec <string> : and this one, etc.
--include <regex> : sync folders matching this regular expression
--include <regex> : or this one, etc.
in case both --include --exclude options are
use, include is done before.
--exclude <regex> : skips folders matching this regular expression
Several folders to avoid:
--exclude 'fold1|fold2|f3' skips fold1, fold2 and f3.
--exclude <regex> : or this one, etc.
--prefix1 <string> : remove prefix to all destination folders
(usually INBOX. for cyrus imap servers)
use --prefix1 if your source imap server does not
have NAMESPACE capability.
--prefix2 <string> : add prefix to all destination folders
(usually INBOX. for cyrus imap servers)
use --prefix2 if your target imap server does not
have NAMESPACE capability.
--regextrans2 <regex> : Apply the whole regex to each destination folders.
--regextrans2 <regex> : and this one. etc.
When you play with the --regextrans2 option, first
add also the safe options --dry --justfolders
Then, when happy, remove --dry, remove --justfolders
--regexmess <regex> : Apply the whole regex to each message before transfer.
Example : 's/\\000/ /g' # to replace null by space.
--regexmess <regex> : and this one.
--regexmess <regex> : and this one, etc.
--regexflag <regex> : Apply the whole regex to each flags list.
Example : 's/\"Junk"//g' # to remove "Junk" flag.
--regexflag <regex> : and this one, etc.
--sep1 <string> : separator in case namespace is not supported.
--sep2 <string> : idem.
--delete : delete messages on source imap server after
a successful transfer. Useful in case you
want to migrate from one server to another one.
With imap, delete tags messages as deleted, they
are not really deleted. See expunge.
--delete2 : delete messages on the destination imap server that
are not on the source server.
--expunge : expunge messages on source account.
expunge really deletes messages marked deleted.
expunge is made at the beginning on the
source server only. newly transferred messages
are expunged if option --expunge is given.
no expunge is done on destination account but
it will change in future releases.
--expunge1 : expunge messages on source account.
--expunge2 : expunge messages on target account.
--syncinternaldates : sets the internal dates on host2 same as host1
--buffersize <int> : sets the size of a block of I/O.
--maxsize <int> : skip messages larger than <int> bytes
--maxage <int> : skip messages older than <int> days.
final stats (skipped) don't count older messages
see also --minage
--minage <int> : skip messages newer than <int> days.
final stats (skipped) don't count newer messages
You can do (+ are the messages selected):
past|----maxage+++++++++++++++>now
past|+++++++++++++++minage---->now
past|----maxage+++++minage---->now (intersection)
past|++++minage-----maxage++++>now (union)
--skipheader <regex> : Don't take into account header keyword
matching <string> ex: --skipheader 'X.*'
use 'folder:regexp' to apply only to certain folders
--useheader <string> : Use this header to compare messages on both sides.
Ex: Message-ID or Subject or Date.
--useheader <string> and this one, etc.
--skipsize : Don't take message size into account.
--dry : do nothing, just print what would be done.
--subscribed : transfers subscribed folders.
--subscribe : subscribe to the folders transferred on the
"destination" server that are subscribed
on the "source" server.
--(no)foldersizes : Calculate the size of each "From" folder in bytes
and message counts. Meant to be used with
--justfoldersizes. Turned on by default.
--justfoldersizes : exit after printed the folder sizes.
--syncacls : Synchronises acls (Access Control Lists).
--nosyncacls : Does not synchronise acls. This is the default.
--debug : debug mode.
--debugimap : imap debug mode.
--version : print software version.
--justconnect : just connect to both servers and print useful
information. Need only --host1 and --host2 options.
--justfolders : just do things about folders (ignore messages).
--fast : be faster (just does not sync flags).
--split1 <int> : split the requests in several parts on source server.
<int > is the number of messages handled per request.
default is like --split1 1000
--split2 <int> : same thing on the "destination" server.
--nofastio1 : don't use fastio with the "from" server.
--nofastio2 : don't use fastio with the "destination" server.
--timeout <int> : imap connect timeout.
--help : print this.
--tmpfile <string> : file name for temporary message file.
--pidfile <string> : file name for PID file.
Example: to synchronise imap account "foo" on "imap.truc.org"
to imap account "bar" on "imap.trac.org"
$0 \\
--host1 imap.truc.org --user1 foo --passfile1 /etc/secret1 \\
--host2 imap.trac.org --user2 bar --passfile2 /etc/secret2
