Did the recent Mail.dat version change, PostalOne! software update, or Priority Mail price change catch you by surprise? On September 7, 2014, the United States Postal Service® (USPS®) implemented a price adjustment for Priority Mail and also implemented new postage statements for Priority Mail and other classes of mail as well. This change required mailers to update their USPS MDR Client software from the Business Customer Gateway on August 24, 2014. Along with these changes, PostalOne! support for the old 13-1 Mail.dat version ended and the currently supported versions are the new 14-2 version and the prior version of 14-1. Window Book sends out numerous notifications of these changes in advance through these eTips, but there are other resources available as well to help insure these kinds of changes don’t catch you by surprise in the future.
Why the update?
The USPS periodically makes updates to the PostalOne! system to incorporate enhancements and bug fixes. Major updates are performed when there are significant changes to postal rates and/or regulations, such as when the USPS increases their prices in January each year. There are usually at least four PostalOne! software updates during the year: January, April, July, and October. There may also be interim updates to PostalOne! for immediate fixes or other system issues.
The August update was a major change to support new USPS products and services, postage statement changes, and other updates. The postage statement changes took effect on September 7, 2014.
At the same time, the Mail.dat® specification changed from 14-1 to 14-2. For purposes of submitting Mail.dat files to PostalOne!, the table below shows the various Mail.dat version numbers and the dates on which they are supported by PostalOne!
The USPS sends out notifications of all PostalOne! outages and software updates using the DMM Advisory. You can subscribe to the DMM Advisory by sending an email to email@example.com. In addition, detailed information regarding the changes in the PostalOne! software are available on the USPS RIBBS web site. The DMM Advisory also provides notifications on pricing and postage statement changes, as well as Mail.dat and Mail.xml version changes. This information is also available on the RIBBS web site Release Schedule.
When these types of changes are announced, it is important for mailers to pay attention to the PostalOne! outage periods so that you can make adjustments in your mailing operations to accommodate the downtime. It is also extremely important for mailers to download and install the USPS Mail.dat Client software (also sometimes referred to as MD Client or MDR Client) as soon as it is available. This software can be downloaded from the Business Customer Gateway web site. Mailers also need to make any associated updates or configuration changes to software that interfaces with PostalOne! once their Mail.dat Client software is updated. For example, if you use DAT-MAIL’s eDocs Manager Plus or our newly improved EDM10X, you will need to edit the configuration for this in the Window Book Automation Scheduler.
Likewise, mailers need to pay attention to Mail.dat and Mail.xml version changes and USPS data file updates (Labeling Lists, Zone Charts, Drop Ship files, etc.) and coordinate with their presort and post-presort software so that the correct versions are used.
