spamassassin 3.4.0 not idn support yet ?

There is currently (3.4.0) no specific IDN support yet,
mainly because not much of these have been observed in the wild.

If the domain found in a mail body is encoded in punycode,
I see no reason for not being subject to uridnsbl rules, and
if it really isn't it's probably a bug.

If the domain found in a mail body is in Unicode (not encoded
into punycode), such conversion is not yet implemented in
SpamAssassin. Eventually it probably should as these become
widespread, so this would be a feature request.

It would be most welcome to see concrete samples from the wild.
There may already be some IDN-related problem report,
but please do open a new one and attach your samples,
at lease it can get a conversation going.
