Mutt is running on the mailserver.  It submits the outgoing mail to 
localhost.  localhost should relay the mail out to the recipient.

I realize that, hence my post.  The server sends lots of outgoing 
non-local mail.  Just not to the smokeping list subscription 

I had looked at /etc/mail/access prior to posting, but not closely
enough.  It was being denied by an access map entry.
