The method of claim 1, wherein the determined computer at the network address can concurrently convert attachment files from different fax jobs into the file format. 9. The method of claim 1, wherein the facsimile transmission includes message content and a cover page that are converted to images in the file format for transmittal with the attachment files. 10. The method of claim 1 further comprising: maintaining, with the fax management server, a job table including fax job records identified by job number; and changing, with the fax management servers, state fields in the fax job records to manage the workflow of the fax jobs between the fax management system and any computers to which attachment files were sent. 11. The method of claim 1, wherein the fax management system is implemented in a first computer, and wherein each attachment file is converted in at least one computer that is different from the first computer. 12. A method for processing a message in a network computing system including a facsimile transmission comprised of a recipient contact address and one or more attached files, comprising: managing facsimile transmissions as fax jobs in a fax management system; for each attachment file in a fax job, performing: (i) determining, with the fax management system, a network address of a computer including an application program capable of converting the attachment file to at least one image in a file format, wherein different computers at different network addresses are capable of converting different attachment file types to at least one image in the file format, wherein the determination with the fax management system comprises processing a table having entries that each associate a file type with a network address of a computer including the application program capable of converting an attachment file of the associated file type and determining an entry having a file type that matches the file type of the attachment, wherein the table includes a default entry indicating a network address of one computer, and wherein the attachment file is sent to the network address identified in the default entry when there is no entry in the table specifying the file type of the attachment file; (ii) transmitting, with the fax management system, the attachment file to the computer at the determined network address; (iii) executing, with the computer receiving the attachment file, one application program to convert the attachment file to at least one image in a file format; and transferring all the converted attachment files in the message to a communication port for transmittal to the recipient contact address. 13. A system for processing a message in a network computing system including a facsimile transmission comprised of a recipient contact address and one or more attached files, comprising: (a) a fax management system including a processor and a memory coupled to the processor; (b) a plurality of computers, each including a processor and a memory coupled to the processor; (c) at least one communication port in communication with the fax management system; (d) fax management program logic residing in the memory of the fax management system, wherein the fax management program logic, when executed by the fax management processor performs: (i) managing facsimile transmissions as fax jobs in a fax management system; (ii) determining, for each attachment file in a fax job, a network address of one of the plurality of computers including an application program capable of converting the attachment file to at least one image in a file format, wherein different computers at different network addresses are capable of converting different attachment file types to at least
