What user logon name formats does IMSVA support for Active
Directory?
Active Directory supports the following logon name formats:
• Example 1: bob@imsstest.com
Note: The logon name is not an email address (though it appears as one).
• Example 2 (pre-Windows 2000): IMSSTEST\bob
Note: The pre-Windows 2000 format is not supported by Kerberos authentication.
Why are some users unable to use Kerberos SSO?
Users who are bound to SPN (Service Principal Name) cannot use Kerberos SSO.
Spam Protection Service
How is the spam catch rate determined?
Specify a threshold value between 3.0 and 10.0 for IMSVA to classify an email message
as spam. A high threshold value means that a message must be very "spam-like" to be
classified as spam (this decreases the spam catch rate but reduces the likelihood of false
positives). A lower threshold value means that a message only needs to be slightly
"spam-like" to be classified as spam (this increases the spam catch rate and may lead to
more false positives).
