Getting this message
Log Name: Application

Event ID: 1035
Task Category: SmtpReceive
Inbound authentication failed with error LogonDenied for Receive connector My Connector. The authentication mechanism is Ntlm. The source IP address of the client who tried to authenticate to Microsoft Exchange is [10.2.8.17].
The ip address is an internal address on my WSUS server which sends status emails each day.
I also get the same 1035 on some external emails.
The Relay connector was disabled due to the many spam emails I was getting
The Relay connector was what I used on my 2007 exchange server.
The Relay connector was setup to allow all my internal devices to send smtp email to port 25
After switching to 2010 Exchange server I started getting this message.
