I periodically get the following lines in the log. Why is this happening? Wasn't Apple supposed to configure this for me somehow?
Apr 04 14:40:17 imap-login: Info: Disconnected (tried to use unsupported auth mechanism): user=<com.apple.calendarserver>, method=PLAIN, rip=10.0.10.3, lip=10.0.10.3, TLS
Can I fix it?
