For encryption, STARTTLS, which protects more mail than all other email encryption technology combined. See http://www.cs.auckland.ac.nz/~pgut001/pubs/usenix02_slides.pdf (towards the back). For signing, nothing. The S/MIME list debated having posts to the list signed, and decided against it: If I know you, I can recognise a message from you whether it's signed or not. If I don't know you, whether it's signed or not is irrelevant. That leaves a few highly specialised applications which don't really qualify as use by "real people" (e.g. pgpmoose, EDI, etc etc, where any random proprietary format is fine, since it's decided by mutual agreement of both parties).
