How to disable the relay function of Notes 's SMTP port? 


Lotus Software produced the Lotus 1-2-3 spreadsheet program, and later developed Lotus Notes, a groupware and email system. Following its acquisition by IBM, the Notes and Domino client/server collaborative platform were expanded to include functions such as email, calendars, to-do lists, contacts management, teamrooms, discussion forums, file sharing, microblogging, instant messaging, blogs, and user directories. IBM also release SmartSuite, a comprehensive office suite, and followed that with Symphony, unrelated to the Lotus suite of the same name.
