Symptoms include the following error "Job is invalid; no $$ signature" on out going mail.

SOLUTION:

First, be sure you have set up your server set with spool service and not queue service....

The problem is due to NT not liking Novell's naming convention. Look in your pconfig, SMTP Internet Mail Interfaces. The second line marked, Output Path probably looks like:

SERVER\SYS:SMTPMAIL

\\SERVER\SYS\SMTPMAIL
