You have eliminated the most important part of this error message: the name of the complaining process. We can guess that it was "smtpd", as we expect the SMTP server to use keytabs, and the SMTP client to use a credential cache. The error indicates that "smtp/<servername>@REALM" was not found in the keytab file used. Make sure you are using the right keytab file and that it has the expected contents. -- Viktor.
