No, it's simply the matter of how a MUA takes rejection versus MTAs.
Typical MUAs probably cannot distinguish types of rejection. Even a
temporary error comes right back to the user. At least that's the case
in kmail. I think the answer to the OP's question is, "No, not easily."
The workarounds are probably not worth the trouble; either live with
the occasional problem, or remove the reject_unknown_recipient_domain
(One workaround might be a simple policy service which checks the
Internet connection and returns "OK" for mynetworks hosts if the
connection is down.)
