Exchange 2007 not reaching Rackspace servers

I have a customer who I can't send emails to...I think it's on their end but they seem to think it's something w/ the my exchange...

Any suggestion?

Hi,

This is one way to test it: https://testconnectivity.microsoft.com/

Let us know what the result is.
Try send by telnet.
If you don't have telnet installed go to Control Panel and install Windows Feature, add telnet client.

Open telnet

open  (other server IP ) 25
helo
mail from:youremail@yourserver.com
rcpt to:recipientemail@theirserver.com
data
PUT SOME INFORMATION
hit enter
type (dot)   .
Enter
end check for information

Make sure your and their port 25 is open
don't make any errors in typing, telnet don't forgive errors (you can't use backspace to correct)
Or try it using this simple PowerShell command:

Send-MailMessage -From "Sender@PowerShell.domain.com" -To "Recipient@domain.com" -Subject "Testing email relay to external" -Body "Anonymous Email Relay using SMTP.domain.com" -SmtpServer "SMTP.domain.com" -DeliveryNotificationOption OnFailure -Verbose

Open in new window
