Multiple Email Addresses

How do I create multiple email addresses for members of a society whose domain I host? Do I set up multiple mailboxes or mutiple email addresses? How will they each be able to check their mail logging in with their own username or password?

In the control panel go to the Mailboxes tab.
You can create new mail accounts there, and when you create an account, the addresses tab is also updated by the system.

They will then be able to POP their mail, connect via IMAP or use webmail.yourdomain to read their mail on the web.
