Sorry, I assumed that John’s question was about IMAP clients. I agree that there are more UA-ready mail clients in general, even if I’m a little surprised by that list. Last time I tested the ios app (Apple’s, I assume) it was unable to reply correctly, and since I’m typing this into Outlook, let’s test… nope, can’t add a Unicode address to this message, see screenshot. The previous version could do it, and OWA can too.
When I was testing EAI software a while ago, I found almost no IMAP clients or servers that had the EAI extensions, but it hardly mattered since they handled EAI messages and UTF-8 folder names using the regular non-EAI methods. Dovecot, at least up to 2.3, only allows ASCII user names and passwords (I looked at the code.) In 2.4 it should allow them if your client turns on the extension. Any idea if it does even if you don't?
