Emailed to remove ad mocking fragrant resin (5)

I believe the answer is:

elemi

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

'fragrant resin' is the definition.
(I've seen this in another clue)

I can't explain the remainder of the clue.

(Other definitions for elemi that I've seen before include "Fragrant tree resin used as incense - I'm Lee (anag)" , "Tree resin; ie, elm (anag.)" , "Resinous stuff" , "Fragrant resin used as incense - Emile (anag)" , "aromatic resin" .)

I've seen this clue in The Irish Times.
