Welcome to the imapsync web site!
What is imapsync?
imapsync software is a command line tool allowing incremental and
recursive imap transfers from one mailbox to another, both anywhere on the internet
or in your local network.
imapsync is useful for imap account migration or imap account backup.
imapsync is not adequate for maintaining two active imap accounts in synchronization
where the user plays independently on both sides. Use offlineimap
(written by John Goerzen) for this purpose.
Some numbers for 2011
- Number of imapsync users per month: between 2 and 3 thousands users
- Number of imapsync transfers per month: between 3 and 11 millions transfers
- Pourcentage between operating systems users running imapsync:
- Linux: 65 %
- Win32: 18 %
- Darwin: 11 %
- FreeBSD: 6 %
- Solaris: 0.4 %
- OpenBSD: 0.1 %
- Biggest user usage: more than 11 millions of IMAP mailbox transfers

Lists of imap server software failures and success stories
Let's start with reported failure stories over the past.
Maybe new imapsync releases can run successfully with them.
Don't hesitate to have a try, I will help you and make efforts to switch them to the success list.
- DBMail 0.9, 2.0.7 (GPL). But most other DBMail releases are supported (see below)
- Imail 7.04 (maybe).
- MailEnable 1.54 (Proprietary) but MailEnable 4.23 is supported.
- (2011) MDaemon 12.0.3 as host2 but MDaemon is supported as host1. MDaemon is simply buggy with the APPEND IMAP command with any IMAP email client.
