At the top of your RCPT acl:

accept
authenticated = *
control = submission
endpass
verify = sender

This accepts any message sent by an authenticated user, puts the message
in submission mode, and requires that the sender verify (ensuring that
bounces can be delivered). If the sender verification fails, the
message will be denied at SMTP time, but any other delivery failure will
result in a bounce being delivered to the authenticated sender address
($authenticated_id@$qualify_domain) instead.
