If you mean the following: sendmail adds the recipient to the "Received" 
header only, if there is just one recipient, then yes, stream by recipient 
will do.

What I don't understand is the "multidrop mailbox" part. If you alias one 
recipient into multiple local mailboxes, just like:

list: userA, userB, userC

and mail to just one recipient "list", then yes, too, at least in my setup 
:-)

If mean, you alias multiple recipients to one mailbox, just like:

userA: single
userB: single
userC: single

and mail to userA, userB,& userC, then yes, too, but you will get the same 
message three times in the mailbox of the user "single" and the 
"Received:" header will differ in userA, userB,& userC respectively.
stream_by_recipient() splits the message into three individual messages 
and sendmail is no longer able to detect that the message has just one 
drop point.
