When a client first connects to the Messaging Server POP or IMAP port, the server sends an identifying text string to the client. This service banner (not normally displayed to the client’s user) identifies the server as Sun Java System Messaging Server, and gives the server’s version number. The banner is most typically used for client debugging or problem-isolation purposes.
Use the configutil utility (service.imap.banner, service.pop.banner) to set service banners. For detailed syntax information about configutil, see the Sun Java System Messaging Server 6.3 Administration Reference.
