Make synchronization of mailboxes

[LMSSML]

Hi there,

I've got a sendmail server with fedora 9 with squirrelmail and then I've got a new server with postfix and roundcube.

Reading on some sites that the best way of synchronize the two servers and the mailboxes is with imapsync.

I couldn't get it working on fedora but it works on roundcube.

Is there any tool or some way that make this synchronization ?


Thanks in advanced.
