Yes - " no response" is issued by the device.

One of my problems is that I am doing the research on this for the
mail administrator that is convinced that it's not his problem. So I
asked him - why does it work through inbox.com? He answered saying
that it was the device. Sure except it was working just fine before
and nothing about the device has changed.
The administrator said, from looking at the system log, the device is
trying to make a connection with sendmail and then gets timed out.

To be completely neutral - it may be the device. I just want to get
it working again. So, I am looking for Ideas from the community of
users that I may be able to take to the sendmail admin or the device
manufacturer and get it resolved.

Thanks for your reply - I was unsure if this post would get any
replies. So, If you have a list of things that I could forward to my
administrator for him to check , that would be great.

Hmm, because you unfortunately get no syslog, I would start to sniff
the connection.

Because the reply was that sendmail logged something, I suspect that
this is not a firewall issue. Is there a router, switch, firewall or
something like that between the mail server and the device?

If you see that the device opens the connection, time how long it
takes that the connection times out and if there really is no further
communication.

If the device times out before it receives the greeting from the mail
server, try Andrews advice to ask about the greet pause setting of
sendmail.

Next check, if the device erroreously connects to the smtps (or ssmtp
nowadays?) port 465 instead of the usual 25 (or 587).

Ask for:
1) sendmail's log file entries generated by the device sending attempts
2) track of TCP packets exchanged during sending attempt

To diagnose your problem it is crucial to know in which moment of SMTP
session the problem occurs (after which command/operation).
The fix may be quite different if the delay (no response) concerns
* SMTP greeting
* "mail from" or "rcpt to" reply
* "data" or "the final dot" replies

You should "narrow down" area of trouble search to get meaningful
replies unless you are lucky to find somebody who fixed such problem
with the same device.
