User-Specific Do-Not-Send NDX look-up
The look-up checks for phone number, e-mail address or e-mail domain name for outbound operations controlled by a specific user (.USR) or user job properties (.UJP) file, and if found in the specified index file the outbound operation will fail.
Specifying User-Specific Do-Not-Send look-up NDX files
There are no default files. You must always specify an NDX filename to use this feature.
For phone number look-ups, used for fax, voice and polling outbound operations, the user-specific NDX file is specified on the $dns_file command.
The key field of the phone number NDX file should be numeric; that of the other two files should be character format, with lower case values.
A missing file will cause all look-ups to succeed, so that all transmissions will fail.
Do-Not-Send NDX file maintenance
The PIN command-line utility program provides a simple way to maintain NDX files for this purpose. It can be used in a command file and the DNSADD example application demonstrates how to maintain an NDX file using IVR.
Do-Not-Send look-up exclusions
The $dns_file command may be placed in an FS file with a parameter of "none" to suppress the user do-not-send look-up for a specific item. The control variables USER_DNS_MAIL and USER_DNS_DOMN may be assigned a value of NONE in an FS file to exclude the transmission from do-not-send look-up. This may be useful when sending a fax or email to the target to confirm that the exclusion has been recorded. Values of other than NONE on $dns_file or in these FS-file variables are ignored.
