Summary: Clarifications requested

Comments: 

For "domain", "host" and "remote-host", since sieve strings are UTF-8,
are these items expressed in UTF-8 or in ACE encoding?

    "remote-host"
              => Host name of remote SMTP client, if applicable and
                 available.

It would be cleaner if this was explicitly stated to be the FQDN.

    "remote-ip"
              => IP address of remote SMTP client, if applicable and
                 available.

I think the representation should be defined. I assume it will
be dotted-decimal for IPv4, but for IPv6 will it be the format
defined for URIs (RFC 3986) or that defined for SMTP (RFC 2821)?
