Community Server, relay message authenticated

Hello,

I'm trying to enable outgoing mail transfert from my Community Server to
internet users (or internal users).

Community Server is a blog/forum platform running on IIS.

My Community Server is on a dedicated server, running with user
domain\CSAccount.
I use a Exchange 2007 org with a Hub/CAS and a clustered mailbox server SCC.
I set up in the admin interface in order to send mails to my Hub server with
windows authentication and SSL.

I see in the security logs the authentication attemps and it should work.

However, mails are not sent, they are refused by the Hub server with this
message (EXC01 is the Hub server)

Event Type: Warning
Event Source: MSExchangeTransport
Event Category: SmtpReceive
Event ID: 1035
Date: 27/09/2007
Time: 17:14:04
User: N/A
Computer: EXC01
Description:
Inbound authentication failed with error IllegalMessage for Receive
connector Default EXC01. The authentication mechanism is Gssapi. The source
IP address of the client who tried to authenticate to Microsoft Exchange is
[192.168.0.16].

For more information, see Help and Support Center at
http://go.microsoft.com/fwlink/events.asp.

The main problem is this IllegalMessage. I'm unable to find any informations
related to this problem.

I tried to add rights :

[PS] D:\>Get-ADPermission 'Default EXC01' -User 'SUPPORTECH\AgentSupporTech'

Identity User Deny Rights
