Not sure, but I *think* you may need this.  The logs on your
kerberos server should tell you.  You'll see a request for an
unknown principal of the form "mupdate/hostFQDN".

Note you'll also need "pop/FQDN" and "sieve/FQDN" if you want
to use these services.

This needs to be "sasl_keytab", not "keytab".  If you do need a
"mupdate/hostFQDN" principal, it'll need to be in this file.
