i would solve both on the MDA in dbmail as example i can set "j...@example.com" -> deliver_to phyical user_id "j...@example.com" -> alias to "m...@example.com" additionally a sieve-script could discrard messages where from and to matches "m...@example.com" done in 5 minutes depending un your MDA however, the MTA is in my opinion the totally wrong place because even if you got it to work beware of multi-rcpt messages which does not matter/exist in this form after the MDA (dbmail, dovecot..) got the mail via LMTP
