It appears that sarah.ourweb.net, 216.236.255.132, isn't listening on
port 25.  Hold on, let me do a more complete scan.  (If you get
indications of a scan from 72.64.112/29 please don't treat is as abuse).

You are running telnetd, but that only listens on port 23.  If you
want to listen on port 25 you need to be running a mailserver.  Have
you configured or enabled sendmail (or some other MTA) to listen for
mail from the outside world?  What makes you believe that your system
should be listening for SMTP traffic.

As an aside, since you are already running sshd, there really is no
need to run telnetd.  I would recommend turning that off if there
isn't a compelling need to run it.
