[CalendarServer-users] iMIP mail sending failure

3 Jul 2013

      Hello,

I'm very new to calendar server and trying to install & configure it on
CentOS 6.
I could get it working with Thunderbird but the iMIP configuration for
sending mail out from server is not working.

First a little bit about how I setup the calendar server.

I followed the quickstart document to run it using a non-root user.
Only change is that instead of checking out the trunk I checkout the 4.2
release - so that I would get a stable version.

So I'm running 4.2 release with postgres.

I've configured iMIP configuration options for sending and receiving but
whenever I configure a meeting with external attendee, I get following
error in log :

2013-07-03 11:14:23+0530 [-] [caldav-0]  [PooledMemCacheProtocol,client]
[twistedcaldav.scheduling.scheduler#error] Unknown calendar user address:
mailto:abuse@gmail.int
2013-07-03 11:14:23+0530 [-] [caldav-0]  [PooledMemCacheProtocol,client]
[twistedcaldav.scheduling.scheduler.ScheduleResponseQueue#error] Error
during POST for mailto:abuse@gmail.int: Unknown recipient

I know I'm missing some configuration but cannot figure it out.
Please help.

I'm pasting entire caldavd-dev.plist below. The calendar server is running
on ip 192.168.0.19 and mail server is on 192.168.0.18. There is no log
about connection on the mail server.

Thanks in advance,
Amol.
