For some reason starting early this morning all of our outbound email has stopped sending and instead is queueing up in the "Internet Mail Gateway". Inbound email is working fine and local email within the domain is working fine. No changes have been made to the server in many months. I cannot figure out what is going on here! We are running Scalix 11
EDIT: We are running Scalix 11.0.0 on Red Hat Linux Enterprise 4 - been running fine since Scalix 11 release a few months ago.

"mailq" shows 1 message (I changed the email addresses in the output below for security):

I ran "sendmail -q" and the queue is not emptying (not sure if that is the problem).
