Introduction
Dat-Mail periodically undergoes updates that effect document uploads to Postal One.
For Full Service customers operating Dat-Mail to upload mail.dat files, the version type needs to be updated within Dat-Mail's settings. If a mail.dat file has been uploaded after this update, it will need to be re-uploaded after the version is updated.
