If you search the forums here you'll see that this is discussed at length. You're sending from an email address that doesn't exist. Checking for this in the mail logs and providing the full log message may help us narrow down where the problem is.

Yes, the error message tells you what the problem is. I've seen a simple spelling or typing error cause this.

Hello

Yes, the previous posts are accurate. I will add that you may want to verify the domain name is correctly populated in the /etc/localdomains or /etc/remotedomains file depending on where it's email is handled.

Thank you.
