A comma-separated list of the recipient addresses of the current short message.
The RecipientAddress property can be used for setting single or multiple recipients. It is a comma-separated list of addresses whose format depends on the value of RecipientType.
For a recipient type of normal, the values in RecipientAddress should be either the dotted IPv4 of an SMS-enabled device or the directory number of a target mobile phone. For distributed lists, the value should be the name of the list as it is stored on the SMPPServer.
This property is not available in the Receiver.
