Notification Server 6.0 SP3 R8
Helpdesk 6.0 SP5


The SMTP mail server was failing some email addresses as not being "Authoritative"


Use the Notification Server SMTPLogging feature as described in KB article 2457.

When the SMTP server tried to send to several email addresses, the the error returned was the "Unable to relay."

Configured these addresses as "Authoritative" on the SMTP server and the errors went away; Helpdesk was able to send emails.
