Name:
imapsync - Email IMAP tool for syncing, copying, migrating and archiving
email mailboxes between two imap servers, one way, and without duplicates.
Version:
This documentation refers to Imapsync $Revision: 2.178 $
Usage:
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"
do:
imapsync \
--host1 test1.lamiral.info --user1 test1 --password1 secret1 \
--host2 test2.lamiral.info --user2 test2 --password2 secret2
Options:
usage: imapsync [options]
The standard options are the six values forming the credentials. Three
values on each side are needed in order to login into the IMAP servers.
These six values are a hostname, a username, and a password, two times.
Conventions used in the following descriptions of the options:
str means string
int means integer number
flo means float number
reg means regular expression
cmd means command
--dry : Makes imapsync doing nothing for real; it just print what
would be done without --dry.
Options/credentials:
--host1 str : Source or "from" imap server.
--port1 int : Port to connect on host1.
Optional since default ports are the
well known ports imap/143 or imaps/993.
--user1 str : User to login on host1.
--password1 str : Password of user1.
--host2 str : "destination" imap server.
--port2 int : Port to connect on host2. Optional
--user2 str : User to login on host2.
--password2 str : Password of user2.
--showpasswords : Shows passwords on output instead of "MASKED".
Useful to restart a complete run by just reading
the command line used in the log,
or to debug passwords.
It's not a secure practice at all!
--passfile1 str : Password file for the user1. It must contain the
password on the first line. This option avoids showing
the password on the command line like --password1 does.
--passfile2 str : Password file for the user2.
You can also pass the passwords in the environment variables
IMAPSYNC_PASSWORD1 and IMAPSYNC_PASSWORD2. If you don't pass the user1
password via --password1 nor --passfile1 nor $IMAPSYNC_PASSWORD1 then
imapsync will prompt to enter the password on the terminal. Same thing for
user2 password.
Options/encryption:
--nossl1 : Do not use a SSL connection on host1.
--ssl1 : Use a SSL connection on host1. On by default if possible.
--nossl2 : Do not use a SSL connection on host2.
--ssl2 : Use a SSL connection on host2. On by default if possible.
--notls1 : Do not use a TLS connection on host1.
--tls1 : Use a TLS connection on host1. On by default if possible.
--notls2 : Do not use a TLS connection on host2.
--tls2 : Use a TLS connection on host2. On by default if possible.
--debugssl int : SSL debug mode from 0 to 4.
--sslargs1 str : Pass any ssl parameter for host1 ssl or tls connection. Example:
--sslargs1 SSL_verify_mode=1 --sslargs1 SSL_version=SSLv3
See all possibilities in the new() method of IO::Socket::SSL
http://search.cpan.org/perldoc?IO::Socket::SSL#Description_Of_Methods
--sslargs2 str : Pass any ssl parameter for host2 ssl or tls connection.
See --sslargs1
Options/authentication:
--authmech1 str : Auth mechanism to use with host1:
PLAIN, LOGIN, CRAM-MD5 etc. Use UPPERCASE.
--authmech2 str : Auth mechanism to use with host2. See --authmech1
--authuser1 str : User to auth with on host1 (admin user).
Avoid using --authmech1 SOMETHING with --authuser1.
--authuser2 str : User to auth with on host2 (admin user).
--proxyauth1 : Use proxyauth on host1. Requires --authuser1.
Required by Sun/iPlanet/Netscape IMAP servers to
be able to use an administrative user.
--proxyauth2 : Use proxyauth on host2. Requires --authuser2.
--authmd51 : Use MD5 authentication for host1.
--authmd52 : Use MD5 authentication for host2.
--domain1 str : Domain on host1 (NTLM authentication).
--domain2 str : Domain on host2 (NTLM authentication).
--oauthaccesstoken1 str : The access token to authenticate with OAUTH2.
It will be combined with the --user1 value to form the
string to pass with XOAUTH2 authentication.
The password given by --password1 or --passfile1
is ignored.
Instead of the access token itself, the value can be a
file containing the access token on the first line.
If the value is a file, imapsync reads its first line
and take this line as the access token. The advantage
of the file is that if the access token changes then
imapsync can read it again when it needs to reconnect
during a run.
--oauthaccesstoken2 str : same thing as --oauthaccesstoken1
--oauthdirect1 str : The direct string to pass with XOAUTH2 authentication.
The password given by --password1 or --passfile1 and
the user given by --user1 are ignored.
--oauthdirect2 str : same thing as oauthdirect1
Options/folders:
--folder str : Sync this folder.
--folder str : and this one, etc.
--folderrec str : Sync this folder recursively.
--folderrec str : and this one, etc.
--folderfirst str : Sync this folder first. Ex. --folderfirst "INBOX"
--folderfirst str : then this one, etc.
--folderlast str : Sync this folder last. --folderlast "[Gmail]/All Mail"
--folderlast str : then this one, etc.
--nomixfolders : Do not merge folders when host1 is case-sensitive
while host2 is not (like Exchange). Only the first
similar folder is synced (example: with folders
"Sent", "SENT" and "sent"
on host1 only "Sent" will be synced to host2).
--skipemptyfolders : Empty host1 folders are not created on host2.
--include reg : Sync folders matching this regular expression
--include reg : or this one, etc.
If both --include --exclude options are used, then
include is done before.
--exclude reg : Skips folders matching this regular expression
Several folders to avoid:
--exclude 'fold1|fold2|f3' skips fold1, fold2 and f3.
--exclude reg : or this one, etc.
--automap : guesses folders mapping, for folders well known as
"Sent", "Junk", "Drafts", "All", "Archive", "Flagged".
--f1f2 str1=str2 : Force folder str1 to be synced to str2,
--f1f2 overrides --automap and --regextrans2.
Use several --f1f2 options to map several folders.
Option --f1f2 is a one to one only folder mapping,
str1 and str2 have to be full path folder names.
--subfolder2 str : Syncs the whole host1 folders hierarchy under the
host2 folder named str.
It does it internally by adding three
--regextrans2 options before all others.
Add --debug to see what's really going on.
--subfolder1 str : Syncs the host1 folders hierarchy which is under folder
str to the root hierarchy of host2.
It's the couterpart of a sync done by --subfolder2
when doing it in the reverse order.
Backup/Restore scenario:
Use --subfolder2 str for a backup to the folder str
on host2. Then use --subfolder1 str for restoring
from the folder str, after inverting
host1/host2 user1/user2 values.
--subscribed : Transfers subscribed folders.
--subscribe : Subscribe to the folders transferred on the
host2 that are subscribed on host1. On by default.
--subscribeall : Subscribe to the folders transferred on the
host2 even if they are not subscribed on host1.
--prefix1 str : Remove prefix str to all destination folders,
usually "INBOX." or "INBOX/" or an empty string "".
imapsync guesses the prefix if host1 imap server
does not have NAMESPACE capability. So this option
should not be used most of the time.
--prefix2 str : Add prefix to all host2 folders. See --prefix1
--sep1 str : Host1 separator. This option should not be used
most of the time.
Imapsync gets the separator from the server itself,
by using NAMESPACE, or it tries to guess it
from the folders listing (it counts
characters / . \\ \ in folder names and choose the
more frequent, or finally / if nothing is found.
--sep2 str : Host2 separator. See --sep1
--regextrans2 reg : Apply the whole regex to each destination folders.
--regextrans2 reg : and this one. etc.
When you play with the --regextrans2 option, first
add also the safe options --dry --justfolders
Then, when happy, remove --dry for a run, then
remove --justfolders for the next ones.
Have in mind that --regextrans2 is applied after
the automatic prefix and separator inversion.
For examples see:
https://imapsync.lamiral.info/FAQ.d/FAQ.Folders_Mapping.txt
Options/folders sizes:
--nofoldersizes : Do not calculate the size of each folder at the
beginning of the sync. Default is to calculate them.
--nofoldersizesatend: Do not calculate the size of each folder at the
end of the sync. Default is to calculate them.
--justfoldersizes : Exit after having printed the initial folder sizes.
Options/tmp:
--tmpdir str : Where to store temporary files and subdirectories.
Will be created if it doesn't exist.
Default is system specific, Unix is /tmp but
/tmp is often too small and deleted at reboot.
--tmpdir /var/tmp should be better.
--pidfile str : The file where imapsync pid is written,
it can be dirname/filename complete path.
The default name is imapsync.pid in tmpdir.
--pidfilelocking : Abort if pidfile already exists. Useful to avoid
concurrent transfers on the same mailbox.
Options/log:
--nolog : Turn off logging on file
--logfile str : Change the default log filename (can be dirname/filename).
--logdir str : Change the default log directory. Default is LOG_imapsync/
The default logfile name is for example
LOG_imapsync/2019_12_22_23_57_59_532_user1_user2.txt
where:
2019_12_22_23_57_59_532 is nearly the date of the start
YYYY_MM_DD_HH_MM_SS_mmm
year_month_day_hour_minute_seconde_millisecond
and user1 user2 are the --user1 --user2 values.
Options/messages:
--skipmess reg : Skips messages matching the regex.
Example: 'm/[\x80-\xff]/' # to avoid 8bits messages.
--skipmess is applied before --regexmess
--skipmess reg : or this one, etc.
--skipcrossduplicates : Avoid copying messages that are already copied
in another folder, good from Gmail to XYZ when
XYZ is not also Gmail.
Activated with --gmail1 unless --noskipcrossduplicates
--debugcrossduplicates : Prints which messages (UIDs) are skipped with
--skipcrossduplicates and in what other folders
they are.
--pipemess cmd : Apply this cmd command to each message content
before the copy.
--pipemess cmd : and this one, etc.
With several --pipemess, the output of each cmd
command (STDOUT) is given to the input (STDIN)
of the next command.
For example,
--pipemess cmd1 --pipemess cmd2 --pipemess cmd3
is like a Unix pipe:
"cat message | cmd1 | cmd2 | cmd3"
--disarmreadreceipts : Disarms read receipts (host2 Exchange issue)
--regexmess reg : Apply the whole regex to each message before transfer.
Example: 's/\000/ /g' # to replace null characters
by spaces.
--regexmess reg : and this one, etc.
--truncmess int : truncates messages when their size exceed the int
value, specified in bytes. Good to sync too big
messages or to "suppress" attachments.
Have in mind that this way, messages become
uncoherent somehow.
Options/labels:
Gmail present labels as folders in imap. Imapsync can accelerate the sync
by syncing X-GM-LABELS, it will avoid to transfer messages when they are
already on host2 in another folder.
--synclabels : Syncs also Gmail labels when a message is copied to host2.
Activated by default with --gmail1 --gmail2 unless
--nosynclabels is added.
--resynclabels : Resyncs Gmail labels when a message is already on host2.
Activated by default with --gmail1 --gmail2 unless
--noresynclabels is added.
For Gmail syncs, see also:
https://imapsync.lamiral.info/FAQ.d/FAQ.Gmail.txt
Options/flags:
If you encounter flag problems see also:
https://imapsync.lamiral.info/FAQ.d/FAQ.Flags.txt
--regexflag reg : Apply the whole regex to each flags list.
Example: 's/"Junk"//g' # to remove "Junk" flag.
--regexflag reg : then this one, etc.
--resyncflags : Resync flags for already transferred messages.
On by default.
--noresyncflags : Do not resync flags for already transferred messages.
May be useful when a user has already started to play
with its host2 account.
--filterbuggyflags : Filter flags known to be buggy and generators of errors
"BAD Invalid system flag" or "NO APPEND Invalid flag list".
Options/deletions:
--delete1 : Deletes messages on host1 server after a successful
transfer. Option --delete1 has the following behavior:
it marks messages as deleted with the IMAP flag
\Deleted, then messages are really deleted with an
EXPUNGE IMAP command. If expunging after each message
slows down too much the sync then use
--noexpungeaftereach to speed up, expunging will then be
done only twice per folder, one at the beginning and
one at the end of a folder sync.
--expunge1 : Expunge messages on host1 just before syncing a folder.
Expunge is done per folder.
Expunge aims is to really delete messages marked deleted.
An expunge is also done after each message copied
if option --delete1 is set (unless --noexpungeaftereach).
--noexpunge1 : Do not expunge messages on host1.
--delete1emptyfolders : Deletes empty folders on host1, INBOX excepted.
Useful with --delete1 since what remains on host1
is only what failed to be synced.
--delete2 : Delete messages in the host2 account that are not in
the host1 account. Useful for backup or pre-sync.
--delete2 implies --uidexpunge2
--delete2duplicates : Deletes messages in host2 that are duplicates in host2.
Works only without --useuid since duplicates are
detected with an header part of each message.
NB: --delete2duplicates is far less violent than --delete2
since it removes only duplicates.
--delete2folders : Delete folders in host2 that are not in host1.
For safety, first try it like this, it is safe:
--delete2folders --dry --justfolders --nofoldersizes
and see what folders will be deleted.
--delete2foldersonly reg : Delete only folders matching the regex reg.
Example: --delete2foldersonly "/^Junk$|^INBOX.Junk$/"
This option activates --delete2folders
--delete2foldersbutnot reg : Do not delete folders matching the regex rex.
Example: --delete2foldersbutnot "/Tasks$|Contacts$|Foo$/"
This option activates --delete2folders
--noexpunge2 : Do not expunge messages on host2.
--nouidexpunge2 : Do not uidexpunge messages on the host2 account
that are not on the host1 account.
Options/dates:
If you encounter problems with dates, see also:
https://imapsync.lamiral.info/FAQ.d/FAQ.Dates.txt
--syncinternaldates : Sets the internal dates on host2 as the same as host1.
Turned on by default. Internal date is the date
a message arrived on a host (Unix mtime usually).
--idatefromheader : Sets the internal dates on host2 as same as the
ones in "Date:" headers.
Options/message selection:
--maxsize int : Skip messages larger (or equal) than int bytes
--minsize int : Skip messages smaller (or equal) 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 (+ zone are the messages selected):
past|----maxage+++++++++++++++>now
past|+++++++++++++++minage---->now
past|----maxage+++++minage---->now (intersection)
past|++++minage-----maxage++++>now (union)
--search str : Selects only messages returned by this IMAP SEARCH
command. Applied on both sides.
For a complete set of what can be search see
https://imapsync.lamiral.info/FAQ.d/FAQ.Messages_Selection.txt
--search1 str : Same as --search but for selecting host1 messages only.
--search2 str : Same as --search but for selecting host2 messages only.
So --search CRIT equals --search1 CRIT --search2 CRIT
--noabletosearch : Makes --minage and --maxage options use the internal
dates given by a FETCH imap command instead of the
"Date:" header. Internal date is the arrival date
in the mailbox.
--noabletosearch equals --noabletosearch1 --noabletosearch2
--noabletosearch1 : Like --noabletosearch but for host1 only.
--noabletosearch2 : Like --noabletosearch but for host2 only.
--maxlinelength int : skip messages with a line length longer than int bytes.
RFC 2822 says it must be no more than 1000 bytes but
real life servers and email clients do more.
--useheader str : Use this header to compare messages on both sides.
Example: "Message-Id" or "Received" or "Date".
--useheader str and this one, etc.
--syncduplicates : Sync also duplicates. Off by default.
--usecache : Use cache to speed up next syncs. Off by default.
--nousecache : Do not use cache. Caveat: --useuid --nousecache creates
duplicates on multiple runs.
--useuid : Use UIDs instead of headers as a criterion to recognize
messages. Option --usecache is then implied unless
--nousecache is used.
Options/miscellaneous:
--syncacls : Synchronizes acls (Access Control Lists).
Acls in IMAP are not standardized, be careful
since one acl code on one side may signify something
else on the other one.
--nosyncacls : Does not synchronize acls. This is the default.
--addheader : When a message has no headers to be identified,
--addheader adds a "Message-Id" header,
like "Message-Id: 12345@imapsync", where 12345
is the imap UID of the message on the host1 folder.
Useful to sync folders "Sent" or "Draft".
Options/debugging:
--debug : Debug mode.
--debugfolders : Debug mode for the folders part only.
--debugcontent : Debug content of the messages transferred. Huge output.
--debugflags : Debug mode for flags.
--debugimap1 : IMAP debug mode for host1. Very verbose.
--debugimap2 : IMAP debug mode for host2. Very verbose.
--debugimap : IMAP debug mode for host1 and host2. Twice very verbose.
--debugmemory : Debug mode showing memory consumption after each copy.
--errorsmax int : Exit when int number of errors is reached. Default is 50.
--tests : Run local non-regression tests. Exit code 0 means all ok.
--testslive : Run a live test with test1.lamiral.info imap server.
Useful to check the basics. Needs internet connection.
--testslive6 : Run a live test with ks6ipv6.lamiral.info imap server.
Useful to check the ipv6 connectivity. Needs internet.
Options/specific:
--gmail1 : sets --host1 to Gmail and other options. See FAQ.Gmail.txt
--gmail2 : sets --host2 to Gmail and other options. See FAQ.Gmail.txt
--office1 : sets --host1 to Office365 and other options. See FAQ.Office365.txt
--office2 : sets --host2 to Office365 and other options. See FAQ.Office365.txt
--exchange1 : sets options for Exchange. See FAQ.Exchange.txt
--exchange2 : sets options for Exchange. See FAQ.Exchange.txt
--domino1 : sets options for Domino. See FAQ.Domino.txt
--domino2 : sets options for Domino. See FAQ.Domino.txt
Options/behavior:
--timeout1 flo : Connection timeout in seconds for host1.
Default is 120 and 0 means no timeout at all.
--timeout2 flo : Connection timeout in seconds for host2.
Default is 120 and 0 means no timeout at all.
Caveat, under CGI context, you may encounter a timeout
from the webserver, killing imapsync and the imap connexions.
See the document INSTALL.OnlineUI.txt and search
for "Timeout" for how to deal with this issue.
--keepalive1 : https://metacpan.org/pod/Mail::IMAPClient#Keepalive
Some firewalls and network gears like to timeout connections
prematurely if the connection sits idle.
This option enables SO_KEEPALIVE on the host1 socket.
--keepalive1 is on by default since imapsync release 2.169
Use --nokeepalive1 to disable it.
--keepalive2 : Same as --keepalive2 but for host2.
Use --nokeepalive2 to disable it.
--maxmessagespersecond flo : limits the average number of messages
transferred per second.
--maxbytespersecond int : limits the average transfer rate per second.
--maxbytesafter int : starts --maxbytespersecond limitation only after
--maxbytesafter amount of data transferred.
--maxsleep flo : do not sleep more than int seconds.
On by default, 2 seconds max, like --maxsleep 2
--abort : terminates a previous call still running.
It uses the pidfile to know what process to abort.
--exitwhenover int : Stop syncing and exits when int total bytes
transferred is reached.
--version : Print only the software version.
--noreleasecheck : Do not check for any new imapsync release.
--releasecheck : Check for new imapsync release.
it's an http request to
http://imapsync.lamiral.info/prj/imapsync/VERSION
--noid : Do not send/receive IMAP "ID" command to imap servers.
--justconnect : Just connect to both servers and print useful
information. Need only --host1 and --host2 options.
Obsolete since "imapsync --host1 imaphost" alone
implies --justconnect
--justlogin : Just login to both host1 and host2 with users
credentials, then exit.
--justfolders : Do only things about folders (ignore messages).
--help : print this help.
Example: to synchronize imap account "test1" on "test1.lamiral.info"
to imap account "test2" on "test2.lamiral.info"
with test1 password "secret1"
and test2 password "secret2"
imapsync \
--host1 test1.lamiral.info --user1 test1 --password1 secret1 \
--host2 test2.lamiral.info --user2 test2 --password2 secret2
