ID: ZTN1224

This Zetafax technical note applies to:

  • Zetafax e-mail gateway.


When rendering Acrobat PDF files the following error may occur on the server log.

SYSMAN                - (I) -       QUEUEMAN SEND request SMTPMAIL:~MAIL000.CTL

QUEUEMAN      - (I) -       Completed message SMTPMAIL:~MAIL000 (1 failure)

STMAIL                      - (I) -       Passing message to mail system


The e-mail gateway can not render the document and fails to process the fax message when large Adobe Acrobat document (PDF) files are sent through the e-mail gateway, or more than one PDF file is attached to an e-mail message when sent to the Zetafax e-mail gateway.


There are two possible solutions:

Pre-render the attachments by printing them to the Zetafax printer and saving the file from the client as a G3F file attachment.

Use the Document conversion engine to render PDF documents. This add-on supports over 250 file extensions and is a purchasable add-on to Zetafax.


This has been identified by Equisys as a problem with the software versions given above.
