Re: Regarding "GSSAPI Error" message

Usually GSSAPI refers to Kerberos authentication, but it can be related to other things too (see http://www.faqs.org/faqs/kerberos-faq/general/section-84.html ).

RHEL ES 4 is ready for Kerberos authentication by default - it just needs to be configured. In this case, it would seem that Kerberos authentication is not completely configured.

Is Kerberos in use at the customer site, and is it supposed to be used with sendmail? In other words, is this server supposed to require Kerberos authentication before accepting email from a mail client using SMTP?

If not, there should be no serious impact as the system will fall back to other authentication mechanisms. You might want to disable the Kerberos authentication attempts to avoid this log message.
