=head1 NAME
imapsync - IMAP synchronisation, sync, copy or migration
tool. Synchronise mailboxes between two imap servers. Good
at IMAP migration. More than 36 different IMAP server softwares
supported with success.
$Revision: 1.350 $
=head1 SYNOPSIS
To synchronise imap account "foo" on "imap.truc.org"
to imap account "bar" on "imap.trac.org"
with foo password "secret1"
and bar password "secret2":
imapsync \
--host1 imap.truc.org --user1 foo --password1 secret1 \
--host2 imap.trac.org --user2 bar --password2 secret2
=head1 INSTALL
imapsync works fine under any Unix OS with perl.
imapsync works fine under Windows (2000, XP) with ActiveState's 5.8 Perl
or as a standalone binary software.
imapsync is already available directly on the following distributions
(at least):
FreeBSD, Debian, Ubuntu, Gentoo, NetBSD, Darwin, Mandriva and OpenBSD (yeah!).
Get imapsync at
http://www.linux-france.org/prj/imapsync/
You'll find a compressed tarball called imapsync-x.xx.tgz
where x.xx is the version number. Untar the tarball where
you want (on Unix):
tar xzvf imapsync-x.xx.tgz
Go into the directory imapsync-x.xx and read the INSTALL file.
The INSTALL file is also at
http://www.linux-france.org/prj/imapsync/INSTALL
The freshmeat record is at http://freshmeat.net/projects/imapsync/

=head1 DESCRIPTION
The command imapsync is a tool allowing incremental and
recursive imap transfer from one mailbox to another.
By default all folders are transferred, recursively.
We sometimes need to transfer mailboxes from one imap server to
another. This is called migration.
imapsync is a good tool because it reduces the amount
of data transferred by not transferring a given message if it
is already on both sides. Same headers
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 works well with bad
connections. 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 (--delete2
may help)
=head1 OPTIONS
To get a description of each option just invoke:
imapsync --help
=head1 HISTORY
I wrote imapsync because an enterprise (basystemes) paid me to install
a new imap server without losing huge old mailboxes located on a far
away remote imap server accessible by a low bandwidth 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 life as 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" (with password "secret1")
on host "imap.src.fr" to the imap account "max" (with password "secret2")
on host "imap.dest.fr":
imapsync --host1 imap.src.fr --user1 buddy --password1 secret1 \
--host2 imap.dest.fr --user2 max --password2 secret2
Then you will have max's mailbox updated from buddy's
mailbox.
=head1 SECURITY
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 $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
if CRAM-MD5 is not supported by your imap servers. Use
--ssl1 (or --tls1) and --ssl2 (or --tls2) 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 by default since it
is the only way to go for now. So don't use --authmech1 SOMETHING
with --authuser1 "adminuser", it will not work.
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 an unreliable internet connection, you can use this loop
in a Bourne shell:
while ! imapsync ...; do
echo imapsync not complete
done
=head1 LICENSE
imapsync is free, gratis and open source software cover by

=head1 AUTHOR
Gilles LAMIRAL <lamiral@linux-france.org>
Feedback good or bad is always welcome.
The newsgroup comp.mail.imap may be a good place to talk about
imapsync. I read it when imapsync is concerned.
A better place is the public imapsync mailing-list
(see below).
Gilles LAMIRAL earns his living writing, installing,
configuring and teaching free, open and gratis
softwares. Do not hesitate to pay him for that services.
=head1 BUG REPORT GUIDELINES
Help us to help you: follow the following guidelines.
Report any bugs or feature requests to the public mailing-list
or to the author.
Before reporting bugs, read the FAQ, the README and the
TODO files. http://www.linux-france.org/prj/imapsync/
Upgrade to last imapsync release, maybe the bug
is already fixed.
Upgrade to last Mail-IMAPClient Perl module.
http://search.cpan.org/dist/Mail-IMAPClient/
maybe the bug is already fixed.
Make a good title with word "imapsync" in it (my spam filter won't filter it),
Don't write an email title with just "imapsync" or "problem",
a good title is made of keywords summary, not too long (one visible line).
Don't write imapsync in uppercase in the email title, we'll
know you run windows(tm) and you haven't read the README yet.
Help us to help you: in your report, please include:
- imapsync version.
- output given with --debug --debugimap near the failure point.
Isolate a message or two in a folder 'BUG' and use
imapsync ... --folder 'BUG' --debug --debugimap
- imap server software on both side and their version number.
- imapsync with all the options you use, the full command line
you use (except the passwords of course).
- IMAPClient.pm version.
- operating system running imapsync.
- operating systems on both sides and the third side in case
you run imapsync on a foreign host from the both.
- virtual software context (vmware, xen etc.)
Most of those values can be found as a copy/paste at the begining of the output.
One time in your life, read the paper
"How To Ask Questions The Smart Way"
http://www.catb.org/~esr/faqs/smart-questions.html
and then forget it.

=head1 HUGE MIGRATION
Pay special attention to options
--subscribed
--subscribe
--delete
--delete2
--expunge
--expunge1
--expunge2
--uidexpunge2
--maxage
--minage
--maxsize
--useheader
--fast
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 contains:
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 !

usage: $0 [options]
Several options are mandatory.
--host1 <string> : "from" imap server. Mandatory.
--port1 <int> : port to connect on host1. Default is 143.
--user1 <string> : user to login on host1. Mandatory.
--authuser1 <string> : user to auth with on host1 (admin user).
Avoid using --authmech1 SOMETHING with --authuser1.
--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. Use UPPERCASE.
--authmech2 <string> : auth mechanism to use with host2. See --authmech1
--ssl1 : use an SSL connection on host1.
--ssl2 : use an SSL connection on host2.
--tls1 : use an TLS connection on host1.
--tls2 : use an TLS 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.
--tmpdir <string> : where to store temporary files and subdirectories.
Will be created if it doesn't exist.
Default is system specific and should be ok.
--pidfile <string> : the file where imapsync pid is written.
--prefix1 <string> : remove prefix to all destination folders
(usually INBOX. for cyrus imap servers)
you can 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 host1 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 host2 that are not on
host1 server.
--expunge : expunge messages on host1.
expunge really deletes messages marked deleted.
expunge is made at the beginning, on host1 only.
Newly transferred messages are expunged if
option --expunge is given.
No expunge is done on destination account
(see --expunge2) but it may change in future releases.
--expunge1 : expunge messages on host1.
--expunge2 : expunge messages on host2.
--uidexpunge2 : uidexpunge messages on the destination imap server
that are not on the source server, requires --delete2
--syncinternaldates : sets the internal dates on host2 same as host1.
Turned on by default. Internal date is the date
a message arrived on a host (mtime).
--idatefromheader : sets the internal dates on host2 same as the
"Date:" headers.
--buffersize <int> : sets the size of a block of I/O.
--maxsize <int> : skip messages larger than <int> bytes
--minsize <int> : skip messages smaller 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.*'
--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 to compare
messages on both sides. On by default.
Use --no-skipsize for using size comparaison.
--allowsizemismatch : allow RFC822.SIZE != fetched msg size
consider also --skipsize to avoid duplicate messages
when running syncs more than one time per mailbox
--dry : do nothing, just print what would be done.
--subscribed : transfers subscribed folders.
--subscribe : subscribe to the folders transferred on the
host2 that are subscribed on host1.
--subscribe_all : subscribe to the folders transferred on the
host2 even if they are not subscribed on host1.
--nofoldersizes : Do not calculate the size of each folder in bytes
and message counts. Default is to calculate them.
--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.
--debugimap1 : imap debug mode for host1. imap debug is very verbose.
--debugimap2 : imap debug mode for host2.
--debugimap : imap debug mode for host1 and host2.
--version : print software version.
--noreleasecheck : do not check for new imapsync release (a http request).
--justconnect : just connect to both servers and print useful
information. Need only --host1 and --host2 options.
--justlogin : just login to both host1 and host2 with users
credentials, then exit.
--justfolders : just do things about folders (ignore messages).
--fast : be faster (just does not sync flags of messages
already transfered).
--reconnectretry1 <int>: reconnect to host1 if connection is lost up to
<int> times per imap command (default is 3)
--reconnectretry2 <int>: same as --reconnectretry1 but for host2
--split1 <int> : split the requests in several parts on host1.
<int> is the number of messages handled per request.
default is like --split1 1000.
--split2 <int> : same thing on host2.
--fastio1 : use fastio with host1.
--fastio2 : use fastio with host2.
--timeout <int> : imap connect timeout.
--help : print this help.
Example: to synchronise imap account "foo" on "imap.truc.org"
to imap account "bar" on "imap.trac.org"
with foo password "secret1"
and bar password "secret2"
$0 \\
--host1 imap.truc.org --user1 foo --password1 secret1 \\
--host2 imap.trac.org --user2 bar --password2 secret2
