Hi, I am looking for tools to migrate Mails from one IMAP-Server to another. Until now I have always used imapsync, but it seems very slow. Even over a 2x10GB/s connection I only get speeds of about 600KiB/s, because the programm always pauses betweeen every single mail. Does anyone here have a suggestion for an alternative?
Take a look at mbsync (isync). Very flexible and quite fast. I've also used offlineimap for a long time.

Here is an .offlineimaprc example :
[general] accounts = main
[Account main] localrepository = dstAccount remoterepository = sourceAccount
[Repository sourceAccount] type = IMAP remotehost = old.server.hostname.com remoteuser = old@example.com remotepass = oldpass ssl = no readonly = true
[Repository dstAccount] type = IMAP remotehost = new.server.hostname.com remoteuser = new@example.com remotepass = newpass ssl = no
