SMTP Reject

[waremock]

SMTP Reject – By default Qmail will accept mail for any domain name that is properly listed in the rcpthosts/virthosts file. However, it doesn't verify that the username exists. .......... Plesk has pre-set Qmail to deny accepting the message altogether if the user does not exist on the server.


Is there a way to add any exceptions?

Explain a situation in which you'd WANT to not reject email that is not a valid user on the server?
