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?
We use dovecot dsync for migration on our customer projects. It is fast with enough parallelism and we have been able to saturate 10Gbps links. Also it is the only sync tool available that syncs all data including pop3 uidls.
