Not sure, what you mean in detail.

We successfully receive mail from IDN domain senders over EXIM / Cyrus, while it is typically not a good idea to have any IDN domain in an email address (lack of "standardization" / compatibility). But I’m not sure how reliable this works.

For that what i have seen - not really.

In the past we recommended our users to avoid using i.e. german Umlauts within folder names, even if they seems to get „converted“ by cyrus in a working or even proper manner - there will be problems with several IMAP clients not liking this, which still have problems with that on their side…
