That is a relaying error message. Was that the complete error message? Are
you connected to your ISP when you try to send? It would seem that someone
doesn't like your SMTP settings.

I'm sorry to have to inform you that the message returned
below could not be delivered to one or more destinations.
The e-mail server has responded with the following error:

sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)
Your e-mail message is being returned to you in the next part of this
message. Try to send the message again.

Should you need assistance, please contact your administrator or your
Internet service provider.

You can also verify e-mail client's settings, for instance:
- whether your SMTP autentization has been configured
- whether you have provided correct SMTP server name
- whether the sender's address responds to the used SMTP server domain
