Hmm, at the first sight, postfix uses ICU for two purposes:

(1) ASCII/UTF-8 domain name conversion
(2) casefold UTF-8 text for caseless comparison

(1) can be replaced by idnkit if someone writes wrapper functions.
(2) seems to be lacking from idnkit. We probably can write stripped-
down version of that function, derived from ICU.

Anyhow, it needs some work to enable smptutf8...
