I believe the answer is:

brainbox

I'm a little stuck... Click here to teach me more about this clue!

'for intellectual?' is the definition.

'where emails arrive on underwear' is the wordplay.
I cannot really see how this works, but
'underwear' could be 'bra' (bra is a type of undergarment) and 'bra' is located in the answer.
The remaining letters 'inbox' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for brainbox that I've seen before include "Mastermind" , "Egghead" , "Skull - clever clogs" , "quiz champion?" , "Clever type" .)

I've seen this clue in The Telegraph.
