Objective:  Send email directly to ProtoFax that it will then fax or send to an alphanumeric pager.   Also allow for two different types of email messages: One addressed to a user such as alan@fax.provider.com that will be faxed to the number defined for this user in the ProtoFax userbase and the other addressed to faxnumber@fax.provider.com which will be faxed to faxnumber.  

Discussion:  The ProtoFax Server has a built in SMTP server that allows for multiple configuration options and uses. ProtoFax will fax email that it receives via SMTP to the fax number that you specify in a client's account in the ProtoFax userbase. As an SMTP server, you can place ProtoFax into your network in different configurations. It can accept mail directly from clients or mail that is forwarded from other SMTP servers. The ProtoFax SMTP Server can also be configured to allow the SENDER of the email  message to specify the number to which the message will be faxed. As an example, a client would compose an email message such as:  

To:      591-9217@fax.provider.com  
From:    alan@company.com  
Subject: bigsecret  

This is a sample message.  

Notice that in the above example, a password may be placed in the subject line of the message for further access restriction. This message would get faxed to 591-9217 from the ProtoFax Server fax.provider.com. Full access restrictions are built into ProtoFax to assure that only clients with the appropriate privileges can send faxes. In addition to this, for each client you may define what 'type' of numbers they may or may not send faxes to. For each client, ProtoFax allows you to define the 'logic' that a client's fax number must obey in order to be faxed. For example ProtoFax may allow one client to only fax to 7 digit numbers. Or maybe you may only want to allow another client to fax to any 7 digit  number with the 591 prefix. Or maybe you want to let a certain client fax to any number that they want. ProtoFax will allow you to do all of this.
