IMAP/Sieve-like. (You can't put arithmetic expressions in the rules, for
example.) The other weird bit is that the rules work with the MAPI
representation of the message rather than the MIME representation, which
is why you can't directly compare against arbitrary RFC822 headers, only
the whole PR_TRANSPORT_MESSAGE_HEADERS property.
