Couldn't find much info on this in the manual. What exactly does Tools - Import - ISPConfig 3 Mail do? I'm setting up a brand new server and will be transferring all of the domains and users. The old server started as debian 5 updated to 6 and then 7. And also switched at one point from courier to dovecot. There are a few quirks which I would not like to transfer over, like any spam filtering settings for example. Does this only import the users and passwords? Also I'm assuming I will have to copy the roundcube database to retain any user contacts. Thanks in advance.
