CSSMTP NonDelNotifications without embedded message body

A user tried to send a message containing 84MB of data (several times,
because he did not get any feed back). According to CSSMTP's design the original message of 84MB was included into the notification, which was denied by the target server because it exceeded the max msg size. .
There should be a way to have only the notification being sent back to the sender, without including the original message.

There is an option described in RFC 3461, allowing notifications being sent without appending the original msg:

'RET=HDRS' as trailing parameter in the 'MAIL FROM' command. (CSSMTP does not recognize it)
Is it possible that this option could be implemented in a future version ? It would help to avoid complains from the users about not being notified about errors.

According to that RFC you need not even implement the RFC to send notifications without the message body, it is up to the mailer (CSSMTP) and could be offered as a configurable option:
rfc3461 item 4.3:
'If no RET parameter is supplied, the MTA MAY return either the
headers of the message or the entire message for any DSN containing
indication of failed deliveries.'

However, I think having the client make the decision and implementing the RFC would be the better solution.
