you need to setup a recepient policy for the domain

To where are you trying to send this message?

It sounds more like a filtering problem on the other end. Try changing the subject line wording and send again. Also if there is a text attachment, try zipping it as the attachment and try again.

Luck too you!
I am not sure if any of the above answers are accurate. Sorry what I did not include in the problem description is the following

IN THE OFFICE
1. When I am in the office, I can successfully send e-mail via IMAP to outside clients. e.g. I can send to yahoo, aol etc
2. I can successfully send to any internal email address

OUT OF THE OFFICE (e.g. At Home)
1.  I can successfully send to any internal email address
2. External addresses and I get

You do not have permission to send to this recipient.  For assistance, contact your system administrator.
    <webmail.mycompany.com #5.7.1 smtp;550 5.7.1 Message rejected (no valid recipients).>

That's my problem

the server send an 550 unauthorized error and says the recipient, cannot be reached through the server, this means, a rule prevents you from sending to the desired destination. You need to look at the servers settings.. that's why I suggested a link to exchange configuration.

I worked the the Application support to fixed the problem
I don't know what the policy about this is. the firewall was not part of the question, therefore, we could not give the proper solution.
