CommuniGate Pro Accounts contain one or several Mailboxes. Each Mailbox has its own unique name and it can contain zero or more messages. The POP, IMAP, MAPI, XIMSS, WebUser Interface, and Real-Time Application modules provide access to Account Mailboxes.
Several storage formats can be used for CommuniGate Pro Mailboxes. A multi-Mailbox Account can contain Mailboxes stored in different formats.
Each Account always has the INBOX Mailbox. Any message delivered to a CommuniGate Pro Account is stored in its INBOX Mailbox - unless some Automated Processing Rules instruct the Server to store the message in a different Mailbox.
