Is this Yahoo’s problem?  One of my lists is attempting to send mail to yahoo.

6.0.9 PowerPC

The error was generated on the external (Yahoo) server and means that server had some problems parsing/verifying the return-path address (the SMTP command MAIL FROM parameter). Not related to your CGPro operation.
