FIX: SMTP gateway only supports a single address on the TO line



ID: ZTN1120

This Zetafax technical note applies to:

  • Zetafax to 7.1


Addressing an e-mail message to more than one recipient using the TO line with the Zetafax SMTP gateway, causes the fax to be rejected by the Zetafax e-mail gateway.


The Zetafax SMTP gateway treated the recipients as one invalid address.


This issue is resolved by applying the Zetafax 7.1 SMTP gateway . This is available on the Equisys web site www.equisys.com/updates as a separate download for Zetafax 7 users.

Note: If the TO line contains mixed recipients (e.g. Fax and SMTP e-mail addresses) you will receive a fax confirmation back from the Zetafax e-mail gateway for each e-mail address specified, along with the fax addresses.


Zetafax version 7 is no longer supported by Equisys. This issue is resolved with the latest version of Zetafax. If you wish to upgrade to the latest version of Zetafax please contact the Zetafax distributor for your country for more information or:
