This is what you meant.

a) The Postfix queue manager maintains a limited, short-term list of
   unreachable destinations. This list helps it to avoid unnecessary
   delivery attempts, especially with destinations that have a large mail
   backlog.

b) Postfix sends a mail with at most smtp_destination_recipient_limit
   recipients, mails with larger number of recipients are broken up
   into multiple mails with smtp_destination_recipient_limit
   recipients each.
   
c) Postfix sorts the recipients by domain and then sends the
   multi-recipient mail to the machine handling the mail.
