FIX: Zetadocs Client fails to send to email addresses containing special characters with SMTP



ID: ZTN3593

This Zetadocs technical note applies to:

  • Zetadocs PDF version 8.0 or earlier
  • Zetadocs for NAV (versions 4.0 to 5.0) with the Zetadocs Client version 8.0 or earlier


When using SMTP email integration it is possible to enter an email address containing a special character, but sending of the document will fail saying that the document could not be sent to all recipients.

An example of a valid email address which will cause this error is: test& user@equisys.com.


This problem is caused by some incorrect email address validation code in the SMTP sending module of the Zetadocs Client. The validation code does not conform to current standards.

Information on what is a valid email address according to the RFC2822 standard can be found here:



This issue has been resolved in Zetadocs PDF v8.2, available for download here. This update is available free of charge to existing Software Assurance customers and can be accessed using the password provided in your Software Assurance newsletter.

This fault was corrected in the Zetadocs Client v8.2
