Here is Mark's response from the 27th to your original post on this:

"- response codes can be different for each recipient, avoiding
  the need to force amavisd to generate DSN in certain cases

  e.g. one recipient is accepting mail, the other does not exist:
  * with LMTP: MTA gets 250 for recip1, and 5xx response for recip2;
  * with SMTP: 250 response must be returned, and amavisd generates
               a bounce for recip2

- in case of Postfix, more than one mail (transaction) can be
  transferred without tearing down and reestablishing SMTP session.
  This is an implementation limitation of the Postfix smtp service,
  but not of the lmtp service. It is not a limitation of the SMTP protocol."
