I am using the zimbra calendar and only want to use that feature. My mailserver is good ol stable cyrus/postfix combination.
When posting a new appointment my users get notified. Zimbra sends to postfix->cyrus, works. When you accept/decline the invitation the mail does not get routed back to zimbra.
anyone have the same setup and can point me to some source where I can figure out how to route those mails back to zimbra?
