It's correct, but why is it expected? It's only possible if the process which
accepts the message from the net at large has knowledge of the final delivery
target. This is the case sometimes, and other times not.

qmail-smtpd doesn't have any knowledge of local users. It therefore cannot
reject the message during the initial SMTP conversation. It then bounces the
message if the local user turns out not to exist.
This is all allowed by the SMTP spec.

No, it's not a configuration issue. You simply don't understand that this is
also correct and allowed behaviour, and for obvious reasons, it has to be.
There are many network and software configurations which simply make it
impossible to "know" during the inital SMTP conversation whether the local
part of an address is valid.
