Unwanted messages about upcoming maps (4)

Ross

I believe the answer is:

spam

'unwanted messages' is the definition.
(spam emails)

'upcoming maps' is the wordplay.
'upcoming' says the letters should be written backwards (in a down clue coming up is backwards).
'maps' written backwards gives 'SPAM'.

'about' acts as a link.

(Other definitions for spam that I've seen before include "Possible item from menu" , "Computer junk mail" , "Unwanted e-mails" , "(Send) junk mail" , "Unwelcome approach" .)

I've seen this clue in the Sydney Morning Herald.
