Person sending something, as opposed to one acknowledging delivery? (9)

I believe the answer is:

consigner

'person sending something' is the definition.
(someone sending a consignment)

'opposed to one acknowledging delivery?' is the wordplay.
'opposed to' becomes 'con' (I've seen this in another clue).
'one acknowledging delivery?' becomes 'signer' (someone signing for a delivery).
'con'+'signer'='CONSIGNER'

'as' is the link.

I've seen this clue in The Telegraph.
