Hi All,

Mail in Mountain Lion also saves attachments in another location as well, which 
is much harder to find and go through to delete attachments, especially if you 
have quite a few email accounts as I do  :-)

When you receive a message with attachments, Mail stores the raw source of the 
attachments inside the .emlx message file, and keeps a separate copy of the 
attachment alongside the message file in an Attachments folder (both are buried 
'very' deep within ~/Library/ Mail/V2/). 

~/Library/Mail/V2/ .... select 'one' of your Account Folders (if you have more 
than one account)/then... for an example I'll use my AosIMAP-ronni account path:
~/Library/Mail/V2/AosIMAP-ronni/INBOX.mbox/5457B4B6-xxx-xxxx-xxxx-etc/Data/then 
you find folders 0 to 9/ and inside each of those 9 folders are other folders/ 
click one folder/ Attachments/then another folder/then 2, 2.1 or 2.2?/ and 
there is an attachment (which I can 'control-click'-move to trash). Start again 
on another folder...  OMG drat this for a joke... Heck leave the attachments 
there, I don't have time to go through all these folders to find any 
attachments to delete. 

If you remove attachments from a selected message (by choosing Message > Remove 
Attachments), Mail modifies the .emlx file on disk that contains the message 
and also deletes the separate attachment file.

With Daniel's hint below with attachments in the Mail Downloads folder, you can 
choose when Mail deletes attachment copies in the Mail Downloads folder with 
the "Remove Unedited Downloads" pop-up menu on the Mail > Preferences > General 
pane. 
Choose 'Never' to retain the files indefinitely, or 'After Message is Deleted' 
or 'When Mail Quits' to delete them when you quit Mail.

Cheers,
Ronni
