My mail is hosted on servers running Postfix that I control, so this won't work for everybody. In main.cf: virtual_alias_maps = hash:/etc/postfix/db/virtual_aliases This file is in the same standard aliases(5) file format: zzz-foo@example.com my@real-account.com I started doing this when I moved all of my mail off of Google. It has the advantage (over you+foo@gmail.com) that it doesn't reveal my real mailbox. It does very quickly reveal who shares/sells my e-mail address, though. When that happens, it's simply a matter of deleting the alias from the file.
