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.
Latest release is imapsync
Written on
See ChangeLog to know what's new in details since 2001.
New features or bugfixes since previous release 1.411:
- 1.434
- Bugfix: Changed the way imapsync knows whether a folder exists or not. Exchange might be happy and stop deconnecting for this reason.
- Bugfix: Reconnections are well done in TLS mode now.
- Bugfix: IMAP RFC 3501 and some imap servers require internal dates have a zone data. Default to +0000 when host1 doesn't give it.
- Bugfix: Options --maxsize --minsize now really work with --useuid (1.422 had a cache issue).
- Bugfix: Improved the way imapsync deals with headers:
- Stopped getting first 2KB body of message. Not a good idea in practice.
- If massive get headers fails then take the whole header one by one (instead of body).
- Default is like --useheader "Message-Id" --useheader "Message-ID" (instead of just "Message-Id").
- Use header "Message-Id" and header "Date" as md5 signature when taking the whole header.
- 1.422
- Better default behavior: Option --delete2 implies --expunge2 now (unless --noexpunge2 is given.)
- Better default behavior: Correct flags case to be RFC compliant on host2 if host1 is not (\SEEN -> \Seen)
- Better debug: Added --debugcontent option to avoid debugging content (can be big) with --debug option.
- Better debug: Added --debugflags to permit flag debugging only.
- Bugfix: The APPEND error then the FETCH 0 byte error is fixed
- Bugfix: Options --maxsize --minsize now work with --useuid
- Bugfix: Flag sync of already transfered messages now take care of --maxsize --minsize options
- Bugfix: Added 0 length message tracking when fetching host1 (to avoid frequently "APPEND {0}" recent issues).
- Bugfix: Avoid Inbox vs INBOX case problem ("already exists").
- Bugfix: --proxyauth2 was setting proxyauth1 instead of proxyauth2
Some numbers
- Number of imapsync users per month: between 2 and 3 thousands users
- Number of imapsync transfers per month: between 3 and 8 millions transfers
- Pourcentage of MSWin32 users : 10%
- Biggest user usage: 5 millions of transfers in a month (one every 2 seconds)
