Server IP Address This is the IP address of a local mail host. If you do not list every mail host on your machine, you will have mail delivery problems. 196.12.34.56 TextR,W
Directory Specifies the name of a sub-directory of the MailRoot specified in the global mail settings. Each mail host should have its own separate sub-directory to contain its mailboxes. maildir TextR,W
Realm Each mail host can have its own separate user realm. If you leave this setting empty, the default mail realm is used.

With this setting, each mail host has its own set of users and therefore its own set of mailboxes, completely independently of any other mail host on your machine.
