What is imapsync? (back to menu)

Imapsync is an IMAP transfers tool. The purpose of imapsync is to migrate IMAP accounts or to backup IMAP accounts. IMAP is one of the three current standard protocols to access mailboxes, the two other are POP3 and HTTP with webmails, webmails are often tied to an IMAP server.

Latest imapsync release 1.684 was written on Thursday, 17-Mar-2016 09:36:22 CET

Imapsync software is a command line tool that allows incremental and recursive IMAP transfers from one mailbox to another, both anywhere on the internet or in your local network. Imapsync runs on Windows, Linux, Mac OS X. "Incremental" means you can stop the transfer at any time and restart it later efficiently. "Recursive" means the complete folders hierarchy can be copied. "Command line" means it's not a graphical tool, on Windows you have to run imapsync from a batch file.

Imapsync can't migrate Contacts and Calendars. Most email systems don't set or get Contacts or Calendars via the IMAP protocol. No way via IMAP, no way via imapsync but it can be done with other tools or via export/import of csv or ics files. Also consider asking experts at Sumatra company.

imapsync is not suitable for maintaining a synchronization between two active imap accounts while the user is working on both sides. Use offlineimap (written by John Goerzen) or mbsync (written by Michael R. Elkins) for bidirectionnal (2 ways) synchronizations.

Alternatives to imapsync are listed in the Similar softwares section.

Facts and figures (back to menu)

Where all those numbers come from? To know whether a newer imapsync exists or not, imapsync does a http GET to the file VERSION. Via the User-agent parameter it also sends:

You can remove this behavior by adding option --noreleasecheck on the command line (or by setting $releasecheck = 0 in the source code). Check CVE-2013-4279.

How to transfer a single mailbox on Windows (back to menu)

After Imapsync installation, a basic (and really working) example in a DOS window is the following:

.\imapsync.exe --host1 test1.lamiral.info  --user1 test1 --password1  "secret1" ^
               --host2 test2.lamiral.info  --user2 test2 --password2  "secret2" 

But it's better to edit a batch file and run it by a double-click. Take this batch file example imapsync_example.bat and adapt with your own parameters.

How to transfer a single mailbox on Linux/Unix (back to menu)

After Imapsync installation, a basic (and really working) example in a shell terminal is the following:

./imapsync --host1 test1.lamiral.info  --user1 test1 --password1  "secret1" \
           --host2 test2.lamiral.info  --user2 test2 --password2  "secret2" 

But it's better to edit a shell script and run it in a terminal. Take this Bourne shell script example imapsync_example.sh and adapt with your own parameters.

How to transfer many mailboxes (back to menu)

In order to migrate many mailboxes, you should use a loop over a csv file containing only the data credentials.
On Windows, see sync_loop_windows.bat batch example.
On Unix, see sync_loop_unix.sh example.
An example of this csv file is file.txt, it can be used with the two previous command scripts.
