Correct. The SMTP server you're delivering the messages through, intramail.cis.cat.com, is checking the value passed in the Mail From command against a list of email addresses on the server. If the Sender value doesn't match an existing email address on the SMTP server, it's rejecting the SMTP request with the "User Unknown" message.

How can I change the the sender value?

Curious about the user unknown error. OPERATIONS is the user name logged in on the computer. The sender field is %LOGINUSER%. Is the SMTP server authenticating the sender?
