I'm attempting to setup IM for our medium sized company.  I've been running ICS for about 1 month now, with very few problems.  I just upgraded to ICS 2.21 which includes IM 2.04.  The program installs good, I've opened port 5177 on my firewall for all users, and communication to the IM/IMail server appears good (everything else is working 100%).  But when attempting to login with user@mycompany.com, I get an invalid user error.  I did almost zero setup on the IM server as it appeared to get all the information it needed from the ICS/IMail database.  The host name is correct, and there are no aliases needed or setup.

It would be very nice if I could at least see the user list, which appears to be blanked when using the IMail database.

I know that problem, too.

We decided to use the IP-Adress from the IM (Imail)-Server. e.g.: user@123.456.789.000

Not nice - but working
