IANA registration is pending, or so the latest draft says. Well,
what'll the draft say if IANA won't hand out port 2000?
I assume you are talking about Manage Sieve protocol.
I see three possibilities:
1. Advise servers to listen to a standard port, and "MAY also listen
to 2000 for legacy compatibility". Advise servers to try the standard
port, then 2000?
2. Advise servers to listen to a standard port, site admins to add a
SRV record, and client to look for the SRV record and fall back to
port 2000 if there is none?
3. Mention only the IANA-assigned port, not 2000, and pretend to
ignore that all servers listen to port 2000 too, and every client
falls back to 2000?
Either 1 or 2 would work for me.
