postDuration property
The number of days a message will be retained before being deleted by this policy. If this value is less than 0, the policy has infinite retention (i.e. messages are never deleted).
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
int? postDuration;
