Subscriber mailboxes represent actual users. You can add multiple mailboxes as easily as individual mailboxes. You also can remove and edit mailboxes with ease.

For each user mailbox, the Administrator can specify how the received faxes should be delivered and, if neccessary, be archived.

You can combine up to fifteen individual users in a group mailbox.
A group mailbox is commonly used to distribute messages to a group of users quickly, in a single step. For example, if a group mailbox is specified as a channel (fax line) operator, then everyone in the group will receive a copy of the received fax message.

A number of subscribers may be combined in a Workgroup Mailbox to work on the same fax document.
A Workgroup Mailbox notifies all members of the arrival of a new fax message. When a member retrieves the fax document for the first time, SilentFax inserts a Retrieval Notification page in front of the fax document. This helps other members know when the fax is being handled and by whom.

An AutoPrint mailbox is designed to obtain a hard copy of the received faxes. Currently only PCL compatible printers are supported.
After printing, an AutoPrint mailbox can optionally forward the fax to another mailbox for backup purposes. It can also generate an email alert when there is a problem with printing.
