However, the following log entry looks suspicious: r4297 | sagen@apple.com | 2009-05-19 23:28:46 +0200 (Di, 19 Mai 2009) | 2 lines Mail gateway's /inbox now requires authentication Is this a bug or is just some additional configuration required? Is it necessary to give full access to the imip user's data using calendarserver_manage_principals? Regards, Markus
