Cant send email

[goodbug]

I can not send outgoing messages. I am using roadrunner as an ISP. Can Any
one offer help? The message is as follows:
The message could not be sent. The authentication setting might not be
correct for your outgoing e-mail [SMTP] server. For help solving this
problem, go to Help, search for "Troubleshoot Windows Mail", and read the
"I'm having problems sending e-mail" section. If you need help determining
the proper server settings, please contact your e-mail service provider.

The rejected e-mail address was '(e-mail address removed)'. Subject
'Re: We are MDR GLOBAL LOGISTICS', Account: 'pop-server.roadrunner.com',
Server: 'smtp-server.roadrunner.com', Protocol: SMTP, Server Response: '450
4.1.8 - Domain of recipient does not resolve [R0309001]', Port: 25,
Secure(SSL): No, Server Error: 450, Error Number: 0x800CCC79

The message indicates "@mrdgloballogistics.com" is invalid. Have you tried
"@mrd-global.com" (seen on their website)?

Change the part of the recipient's email address that says
mrdgloballogistics to mdrgloballogistics.
You swapped the 'r' and the 'd'.
