Turns out that since the machine was on a different subnet, relaying had to
be enabled. Bismark hit the nail on the head with:

Look at your file. You probably are using a relay machine to
get the mail to the outside world. Either get permission on the relay
machine to get mail out, or make your machine the relay machine to the mail.

you may have multiple names for your machine or at least sendmail doesn't
know what you are callng yourself. add teh names of your host to the $=w
class in sendmail. this can be done by adding the host to the
file (if it exists) or by putting a line like:
in the file.

if you are trying to relay from another machine (ie send mail from a

Make sure the localhost is listed in your /etc/mail/access file. If not,
localhost.localdomain RELAY

You didn't give very much information, I would check for this file in
/etc/mail, titled 'relay-domains'. It will contain the name of your domain.
cat /etc/mail/relay-domains

I would look at making sure the E450 is in the /etc/mail/relay-domains file
on the transfer hub that the E450 is trying to send through. Ie- E450 sends
outgoing mail to some server (call it mailhub). /etc/mail/relay-domains on
mailhub needs to contain the E450s hostname.

check what relay machine the delivery agent is attempting to sent.
"/usr/lib/sendmail -v" <> . check
the output.
