Delete Mails in Mac Mail without Trash

Question

How can I delete an email in Mac Mail instantly without moving it to the trash. I don't want to look at the spam crap twice :-)

UPDATE: I want to do this because I have some very old mails in my trash I don't want to delete atm (and decide what to do neither). So I cannot delete my whole trash. But to avoid the trash becoming bigger and bigger I want to delete spam etc. without moving to trash...

Answer 1

Why look in the trash at all? Just set your Trash to automatically delete messages after a day. You can do that in the Accounts pane of preferences:

Answer 2

Delete the message: ⌘⌫

Then empty the trash: ⇧⌘⌫

Answer 3

A very old tip (2006) from MacWorld suggests using Command-V to cut the messages and then just copying some text to wipe the clipboard. This seems to work, but Mail.app tries to copy the contents of those emails to memory - so probably not very useful for lots of mails with attachments etc.
