In the RCPT ACL for your message submission service, put the following:

# Do return address verification.

  require
    verify         = sender

# Check that authenticated users aren't pretending to be someone else.

  deny
    message        = Sender address does not match authenticated user
    authenticated  = *
  ! condition      = ${if and{{ def:sender_address_data } \
                             {{ eq{$sender_address_data}{$authenticated_id}
}} }

In the router that handles email addresses of local users, add

address_data = $local_part
