Hi everybody,

I am trying to send E-Mails to VIBE. In fact I want to add events to a project-calendar, through adding the Mail-Address of the calendar to the list of invited project-members. All rights are set correctly (at least I think so) and as a Mail-Client I'm using GroupWise, but nevertheless I get every time the response-mail: "Message Status - Undeliverable" with the hint: "Response: 530 Authentication required"

Where is my fault?
