Every thread here says to use :fail:. But backscatter says no bounces. So I had to ask. :)

thanks for your time.

If you read the backscatter article carefully, it says to use :fail:....

If yourcompany.tld has a properly configured mail server, the SMTP dialog will look like this:

HELO forged.domain.name
MAIL FROM: [email protected]
RCPT TO: [email protected]
550 User unknown
This is what :fail: does... it denies right at the beginning...

But, if yourcompany.tld doesn’t have a properly configured server, it will accept the email for delivery and then it will be unable to deliver the email to local user "NoSuchUser".
Don't get stuck with the words "NoSuchUser" and think that means :fail: you can put whatever message you like with :fail: such as "Frak-Off"

The big difference in the two above is that the second accepts the email for delivery... :fail: never accepts the message.

So, use :fail: without fail :p
