HOWTO: Configure Zetafax SMTP server with Exchange 2000 and 2003

ID: ZTN1128

This Zetafax technical note applies to:

• 7.00.0.26 or later with Microsoft Exchange 2000 and 2003

Summary

This document will outline the configuration of the Zetafax SMTP server with Exchange 2000/3. As active directory is required for Exchange 2000/3 this assumes that a DNS server has been configured to resolve host names on the network.

SMTP communication over networks for delivering messages requires the use of a name resolution system. HOSTS or DNS can be used to resolve a host, alias or Mail exchanger (MX) record for the Fax name space to address faxes. For example if the domain was domain.com then a fax namespace needs to be configured for fax.domain.com to address e-mail messages from client machines to the fax server. The return path from the Zetafax SMTP server machine needs to be configured to resolve the host for the message reply.

More information

Install the Zetafax SMTP server on Windows NT 4.0 server or Windows 2000/3 server separate from the Exchange server. SMTP requires TCP/IP port 25 to be available and two services cannot share the same port.

Create an 'Alias' or 'MX' record for the Zetafax SMTP server in the DNS server. This could be fax.domain.com where domain.com is the Active directory root.

Check that the FQDN (Fully qualified domain name) for the Zetafax SMTP server can be resolved from the Exchange server using PING or NSLOOKUP (e.g. nslookup fax.domain.com). The utility should return the resolved host name to IP address of the Zetafax SMTP server. Repeat the same check from the Zetafax SMTP server to the FQDN of the Exchange server.

Send a test fax via SMTP to +442072034005@fax.domain.com replacing fax number and domain with your test fax number and mail domain.
