I upgraded to 10.6 Server from 10.5 Server (using "migrate" and Target mode, from a G5 to a Mac Pro). Client Macs have a variety of OS: 10.4, 10.5, 10.6 and 10.7. All those clients can now authenticate AFP connections to the server using Kerberos. But thus far, only clients using 10.4, 10.5 and 10.7 can authenticate SMTP connections using Kerberos. I have 3 clients using 10.6 on Mac Pros, they all can get tickets using kinit no problem, but their Mail cannot send messages unless they switch to MD5. Any ideas?

Mac Pro, Mac OS X (10.6.7), 2 x 3 GHz Dual-Core Intel Xeon 9 GB
