Short story long:

there aren't any!

FYI:

https://mail.google.com/support/bin/answer.py?answer=10313&topic=1564

that was the only reference i found, http://www.ietf.org/rfc/rfc0821.txt
doesn't mention anything beside EXPN which still treats the localpart
literally and checks for a mailbox (or alias) as literally found in the
localpart.

Personally I think google's doing wrong here. Just don't do it anywhere
else, as it's unlikely your mail will reach the person you intended to send
it.
