I get the following message when I try to this email to one of my friends...

The original message was received at Tue, 4 Jan 2000

--- The following addresses had permanent fatal errors ---
----- Transcript of session follows -----
550 someone@somecompany.com... Host unknown (Name server:
somecompany.com: host not found)

This message would likely be the result of a non-existent or mistyped domain. In this case, '@somecompany.com' does not exist. You may want to simply call the recipient of the email and verify their email address with them once again or try sending the email using a different spelling of the '@someonecompany.com'.
