A method and a corresponding system for enabling the sending of messages to a recipient via any of a number of messaging systems of different types are disclosed. In the method addresses for said recipient are stored. Furthermore, recipient availability information is received from the messaging systems. The recipient availability information is interpreted so as to determine in which of the messaging systems the recipient is currently available. Furthermore, an originator input including an identification of the recipient is received and an address among the stored addresses that are associated with messaging systems in which the recipient is currently available is chosen. Finally, the messaging system associated with the chosen address is identified.
