What is imapsync? (back to menu)

Imapsync presentation by Gilles

Imapsync is an IMAP transfer tool.
The purpose of imapsync is to migrate IMAP accounts or to backup IMAP accounts.
IMAP, IMAP4 in fact (started December 1994), is one of the three current standard protocols used to access mailboxes,
the two other being POP3 (started November 1988) and HTTP (started May 1996) with webmails,
webmails are often tied to an IMAP server.

Imapsync 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, without generating duplicates.

“Recursive” means the complete folders hierarchy can be copied, all folders, all subfolders etc.

“Command-line” means it’s not a graphical tool, on Windows you have to run imapsync
from a batch file.
Anyway there is a visual online service,
you can try imapsync online at https://imapsync.lamiral.info/X/

What imapsync can’t do? (back to menu)

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 using caldavsynchronizer
or 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.
See why in the Two Ways Sync document.

Use offlineimap (written by John Goerzen)
or mbsync (written by Michael R. Elkins)
for bidirectional (2 ways) synchronizations.

Imapsync can’t backup nor restore email messages to or from a local directory.
Imapsync works only with IMAP accounts, which always belong to some IMAP server.
Read the Archiving
document to get several solutions, at least four solutions, to this issue.

Alternatives to imapsync are listed in the Similar softwares section.

Alternatives to the imapsync online service
are listed in the External online services section.

Read some other nice and true testimonials from users.

There is no trial version but I offer 30-day money back guarantee whatever the
reason for a refund. Or drop me a gentle email and I will provide you the latest imapsync because,
well, you made the effort to contact me.
After downloading imapsync, go to the installation documentation.

Special offer: it’s only €120 EUR if you buy
imapsync + support at once
(instead of 60 + 120 = 180 EUR).

For €120 EUR you will get:

• Imapsync full professional support (that costs also €120 EUR by itself, see why below).
• Access without any limit to the imapsync online service, like /X.
• Standalone imapsync.exe for win32, easy installation done by a zip extraction anywhere.
  See README_Windows.txt for details.
• Standalone imapsync_bin_Darwin for Mac OS X. (Catalina ok with a permission deed)
• Imapsync Perl source code for any operating system, Unix, Windows, OS X.
• The visual interface, similar to /X,
  to install the service on your own Linux server (not working on Windows yet).
• Lifetime of imapsync updates without extra payment.
• 30-day money back guarantee! No question nor condition to get a refund, really, just request it and you’ll sure get a refund!
• No limit to do anything with imapsync and its license.

For €60 EUR you will get all the above except imapsync full professional support (the first line).

For €120 EUR independently, you get imapsync full professional support,
provided by the imapsync designer and developer, Gilles LAMIRAL, your servitor, who has
been supporting imap migrations with imapsync for more than 20 years (I started in 2001).
See a detailed support description below.

You may wonder why the support alone is the same price as imapsync+support?

It’s because when you buy both at once, I’m not sure I will have to spend some time
directly with you, it’s possible that everything goes smoothly for you,
since this aim is my daily work.
But when you buy the support alone, after buying the software,
then I will surely spend time (any amount of hours) to help you.
Does it seem fair enough?
