September 2019 Releases

Release information for the September 2019 deployment.

There is an optional updated Mail.dat client with this release, which supports implementation of a verification list and new warning message for ineligible Informed Delivery campaigns through the PostalOne! System (CR 13523, Section 3.2). The existing Mail.dat client will not process the warning as part of the receipt; and mailers using the existing Mail.dat client will not have visibility into the status of campaigns that fail due to ineligible Mailer IDs (MIDs). Users can continue to use Mail.dat client 49.1.0.0_PROD, or may download the optional updated client 49.1.1.0_PROD. Both are available from the Business Customer Gateway (BCG) using the following path: Mailing Services è Electronic Data Exchange [Go to Service] è Mail.dat download (Windows 32-bit, Windows 64-bit or Solaris).
