The custom recipient address is in the following format:

UserID

The name of the MSN member. For example, [MSN:patsmith].

MSN allows the sender to change the recipient's display name by using the following addressing style: Pat Smith[MSN:PatSm]. This will resolve on the client to a friendly name of 'Pat Smith' and an address alias of PatSm. The recipient will see the friendly name when they read the message.
