Reportedly mailed perfume (5)
I believe the answer is:
scent
'perfume' is the definition.
('scent' can be a synonym of 'perfume')
'reportedly mailed' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'mailed' becomes 'sent' ('send' can be a synonym of 'mail').
'sent' is a homophone of 'SCENT'.
(Other definitions for scent that I've seen before include "Trail" , "Get wind of" , "Pleasant odour" , "Bouquet" , "Fragrance" .)
