Explanation of the “Security failure. Data decryption error” received with Internet Explorer on a Macintosh OS 9 computer.
To use PSMAIL with Mac OS X, you will need to use a more recent browser such as Safari, Firefox, iCab, or Camino. This is due to the security measures (SSL encryption) for PSMAIL’s login. Internet Explorer for Macintosh does not support encryption.
If you do not have access to any of the suggested browsers above, please contact PSMail’s helpdesk. Some compatible browsers can be downloaded free of charge and we can direct you as needed.
