I accidentally deleted your previous message where you asked about this.
I18NLEVEL=1 is correct. Currently, there are servers that implement
SORT/THREAD in accordance with the requirements of I18NLEVEL=1, but do not
advertise I18NLEVEL=1. We want those servers to upgrade sooner, rather
than later, when imap-i18n (finally) comes out; because there is an
ambiguity that a server might advertise SORT/THREAD without complying with
Note the next paragraph:
Discussion: the SORT and THREAD extensions predate [IMAP-I18N] by
several years. At the time of this writing, all known server
implementations of SORT and THREAD comply with the rules of
I18NLEVEL=1, but do not necessarily advertise it. As discussed
in [IMAP-I18N] section 4.5, all server implementations should
eventually be updated to comply with the I18NLEVEL=2 extension.
I don't think that SORT/THREAD can mandate I18NLEVEL=2 right now, even
with a SHOULD.
