>Description:
        Now, src/etc/services contains following line (by PR#18016):
        sieve           2000/tcp                # RFC3028

        It's wrong, because RFC3028 (superseded by RFC5228) define just
        filtering language, not neither management protocol nor port number.

        The IANA allocated 4190/tcp for ManagerSieve 
(draft-ietf-sieve-managesieve-09), 
        so the entry should be updated.
        (port 2000 was mentioned in old drafts).

>How-To-Repeat:
        compare src/etc/services and
        http://www.iana.org/assignments/port-numbers
>Fix:
        change the line to as following:
        sieve           4190/tcp                # ManageSieve Protocol
        (or sync src/etc/services with IANA).
