> Because when you search through your email, it has to be already decrypted, so why bother? Of course, there's a huge difference between "decrypted on my hard drive" and "decrypted as it passes through N untrusted mail servers". Heck, it doesn't even have to be decrypted on your hard drive in order to be searchable; just use dm-crypt, or TrueCrypt, or PGP, or any of the myriad other full-disk encryption options.
