IMIP on 10.6.2

Question

iMIP. Very sparse documentation. I cannot make it function.
All help welcome. Does it actually work?
Can someone send me a worked example of a working configuration.
I have tried to dechipher making iMIP work for external notification status, but the only clue I get as to what is wrong is this:

I finally got this working under 10.6.3. Here are my invitations settings for iCal Server. I hope they help someone else.
Dont even start until the rest of iCal server is working (calendar, iCal clients). Make sure DNS is perfect before you start.
I copied /etc/caldavd/caldavd.plist.default to /etc/caldavd/caldavd.plist to make sure my previous escapades were removed.
Then in Server Admin:
I set up the base directory, and general settings for iCal Server.
Then in the email invitations settings:
settings
email address: [email protected]
incoming server: localhost
port: 143
SSL: off
user name: com.apple.calendarserver
password: password same as com.apple.calendarserver entry in system keychain (browse in keychain access, open, copy, paste)
outgoing server: localhost
port: 25
SSL: off
user name: com.apple.calendarserver
password: password same as keychain keychain
I was utterly unable to use a different account or user name than this system default one which would have been my preferred option.
*Mail Server considerations*
I had to tell my Mac OS X based mail server to relay ‘localhost’ email I dont think this is a very secure approach. Suggestions welcome.
My whitelisting was off already - think it might have barfed if it was on.
*Server Admin considerations*
I had to turn off SACL's for mail and iCal as part of my debug. Havent turned them back on yet. Don't know how to add 'com.apple.calendarserver' to a group
