If a particular use on IMAP is getting a lot of spam and moves spam into the spam folder does the system learn this globally or only for this particular user?

 

I have 2 servers one acting as a mirror in a remote location, Being a Novice with Linux and Surge mail I did not setup SSH on the server and therefore I can not telnet into it. If I upgrade my Master Server "local" to the newer version and my Mirror remains on the older version will this cause an issue?

 

This will work fine.  Although it's good to update them to match one day there is no immediate problem if you dont.
