I am having some problems with sendmail on a FC 6 machine. When
sending emails to a certain domain:dynavoxtech.com I get a connection
timed out in my logwatch files. Here is a snippet from my maillog:

I turned the sendmail logging up so I could see what was occuring. On
the other end they are seeing this:
204.111.40.3-53920:04182007 10:30:25:Client #76 - 204.111.40.3:53920

notice the connection reset by peer. It shows that they are closing the
connection.
My question is twofold. One is this problem occuring on my mailserver
or on their end? and Two: if it is my problem,what is the issue and
how can I fix it. They are running an ironmail security appliance
from SecureComputing.
