imapsync

imapsync is a tool for facilitating incremental recursive IMAP transfers from one mailbox to another.

imapsync is useful for mailbox migration, and reduces the amount of data transferred by only copying messages that are not present on both servers.

Read, unread, and deleted flags are preserved, and the process can be stopped and resumed. The original messages can optionally be deleted after a successful transfer.

Installation:

imapsync works fine under any Unix OS.

You'll find a compressed tarball called imapsync-x.xx.tgz where x.xx is the version number. Untar the tarball where you want :

tar xzvf imapsync-x.xx.tgz

Go into the directory imapsync-x.xx and read the INSTALL file.

What is new in this release:

• A new --search option was added, allowing you to select messages with the powerful IMAP SEARCH command.
• What can be done is selection by dates, any flag, From, Subject, body string, any Header, sizes, uids, etc.
• Bugs were fixed to better handle folder creation, so it's no longer a failure when a folder "already exists" during its creation.
• The way imapsync deals with headers was improved so that message duplicate issues are now rare.
• Reconnections are well done in TLS mode now.
• Many other small bugfixes and usability improvements were made.
• The default behavior is now the best one for most cases.

What is new in version 1.404:

• This version adds better performance and reliability.
• A --usecache option speeds up transfers when using multiple runs by a factor of at least two.
• A --useuid can be used to speed up or deal with problems using headers (by avoiding duplicate transfers).
• The performance of --usecache when used with MS Exchange was improved.
• A 'not enough memory' issue with big messages was fixed by using the Mail-IMAPClient 3.27 Perl module.
• The license hasn't changed, but Imapsync is no longer gratis from the home page.

What is new in version 1.383:

• Several improvements to reach better usability.
• Authentication cram-md5 is not used by default (too few servers support it).
• Issues from servers changing or adding header are avoided.
• Now imapsync has a way to handle no header in messages efficiently.
• The IMAP server dkimap is supported (dkimap isn't a UID capable server).
• NTLM authentication with domain has been added.
• A --minsize option has been added to transfer messages bigger than a given size.
• Memory consumption measurement has been added to compute how many concurrent imapsync processes can run in parallel on a system.
• Imapsync is no longer gratis from the home page.

What is new in version 1.286:

• Gmail IMAP is now supported.
• This version works fine under Windows XP, and works with Mail::IMAPClient 3.xx and 2.2.9.
• Many bugs were fixed.

What is new in version 1.255:

• Some IMAP servers return a message size that is not equal to the real message size.
• Now imapsync accepts this silly behavior and leaves the message as is.

Requirements:

• Perl
