Sending out emails

[Connie]

I have 3 people I cannot send emails out to. The email address is correct
and others in my company with the same server account have no problem sending
these people emails. What could be the problem. I'm the only one in the
company with VISTA . Error listed below.

A tracert to 66.152.203.19 said it is also known as
Mail.Cooley-Dickinson.org. That's probably the server that's
complaining.

If, on the other hand, the dash before that IP address is
entered as part of the address, tracert will reject it as an
invalid IP address, and I suspect that many other machines
will do this as well.

The error message looks like a complain about the address
you're sending the message to.

Is that all of the error message? If not, click on it and
see if you can copy the whole error message to your
next message.
