Greetings, all:

The Sun patches are available:
105395-08.tar.Z   for Solaris 2.6
107684-08.zip     for Solaris 7
110615-08.zip     for Solaris 8

After applying the patch, I noticed difficulty in sending mail which appears
to have corrected itself after a time. Nothing in the mail server or client
messages logs indicates the nature of the problem.

Best regards,

Walter G. Aiello, Ph.D.
