With a Gmail email@example.com address, you'll also receive email sent to firstname.lastname@example.org addresses, very handy for creating filters.
I often email@example.com when signing up to websites, so if I end up getting lots of spam sent to that address, I know who to blame.
But what's a good way to find a list of all username+anything@ addresses in my Gmail spam folder?
I'd prefer to do this within the web client if possible. Next best is using external client such as Outlook or Opera mail but without having to download lots of mail if possible. I don't really want to download spam emails.
