The issue you're encountering is partially mentioned in the message 
that was distributed to the community about the authentication 
changes:

The detail here is that the valid usernames are for the @mit.edu 
space. As you are using a different namespace, namely math.mit.edu, 
that check will fail regardless of how you authenticated (SSL, 
Kerberos or SSL+Kerberos)

I believe your solution at this time is to use a SMTP service 
provided by math.mit.edu.

For further clarification on this policy, you should contact open a 
case with the Network Group <http://casetracker.mit.edu/>.
