Adding global signature text to outbound messages You can configure Internet Services to append global signature text, such as a disclaimer announcement. The text is appended to all outgoing SMTP messages. The text can be either plain or styled. If you have Internet Services clusters, you can add different global signature text on each service. To add global signature text: 1       Open Internet Services/Global Signature on the administrator's Desktop. If a Global Signature document does not yet exist in Internet Services, create one. 2       Enter your global signature text. 3       Repeat this procedure as required for IS clusters.         The configuration documents for clusters are in the folders contained in Clustered Services on the administrator's Desktop.
