Doing a modification of IMAP and its ACL extension 
is a major undertaking, of course, 
only recommendable to be done if there is no other good way.

RFC4314 (proposed standard) has
  p - post (send mail to submission address for mailbox,
         not enforced by IMAP4 itself)

Considering the implementation, it is the current estimation of my developers, 
that it would be a major effort to add this to Cyrus Imapd.
As far as I have understood, the affected code would be all over the place
which would require a long stabilisation period in case the implementation 
is made.
