When the X-PS-qualifiers: header line is present in a mail message sent to PMDF-FAX, its content is interpreted as a list of command qualifiers for the PMDF PS utility and is passed to the PS utility as such when the message body is processed. Only legal PS command qualifiers can appear in this header line; see the PS utility documentation for a list of legal qualifiers. For example, the header line
If you use PMDF MAIL, PMDF SEND, VMS MAIL, or DECwindows MAIL, you can control the contents of the X-PS-qualifiers: header line with the PMDF_X_PS_QUALIFIERS logical; its translation value at the time the e-mail message is generated is used to form the contents of that header line. See Section 1.1.9 for general information on the use of logical names to specify message header lines.
You can use the PMDF PS utility's /MAIL qualifier to properly set the PMDF_X_PS_QUALIFIERS process logical. Setting the logical this way ensures that only legal qualifiers are placed in the X-PS-qualifiers: header line. See the PS utility documentation in Chapter 8.
