Does MailStream Plus allow you to adjust the value of the Mail.dat field code SEG-1146

Product Affected:  MailStream Plus™
Product Feature: Mail.dat / PostalOne!

No, MailStream Plus™ (MSP) does not allow the person running the job to populate the Mail.dat field code SEG-1146.
The Full-Service Participation Indicator (SEG-1146) values allowed are:
  • Blank = None
  • M = Mixed (Basic and Full Mixed)
  • F = Full Service Option
If the MSP job is setup for Full Service, but MSP finds there are records with no ZIP+4's, then the job has Mixed (Basic and Full Mixed). An M will be populated in the SEG-1146.

Total Records Accepted and Forward            34,413             100.00 % OF PROCESSED
  ZIP+4 Coded Records                         25,698              74.68 % OF FORWARD
