Is there a way I can instruct Postfix to accept incoming mail (external and internal), but not to deliver it/pass the mails on to their respective destinations?
it is not clear which mail you are about. I guess it is about mail received via smtp. if so, use HOLD in a restriction:
smtpd_client_restrictions =
check_client_access pcre:/etc/postfix/hold
== hold:
/./ HOLD
what problem are you trying to solve?
