Q: El Capitan Calendar Server never checks for invitation responses
Quick summary: Calendar Server never checks mail for invitation responses, although they go out fine. How do I get Calendar Server to read its configured email? Server logs show it never it makes an attempt.
I have a brand new El Capitan 10.11.1 install running the current Server 5.0.14. No other software is installed. I am using this only for Calendar service, but have added one mail account to send invitations and receive invitation replies. So, only Calendar and Mail are active as Services.
The email addresses associated with the Calendar users are in a different domain, if that matters.
I can set up an event, with an external invitee, and the invitee will get the invitation. A reply to the invitation is received by the Calendar mail account. (/var/log/mail.log confirms).
However, Calendar Server never checks the mailbox, either via POP or via IMAP. I am monitoring the dovecot logs in /Library/Logs/Mail/mail-info.log to check for the access. It only shows my own (successful) test connections.
Apparently older versions of Calendar Server had a calendar:Scheduling:iMIP:Receiving:PollingSeconds parameter, but this no longer seems to be there (checked via "serveradmin settings calendar"), and trying to set it doesn't seem to do anything.
SSL is active on both the sending and receiving configurations for email (I added a self-signed certificate). The email account works (tested with Mail.app and Seamonkey).
So... how does Calendar Server know when to check the mail account for invitation replies? Is there a normal polling interval? I've left this up for hours, with no luck.
