Comment:
Is this filename encoding really correct? I have same problem, and none of
tried MUAs (including Gmail, Outlook and Kmail) doesn't show filenames
correctly.

> According to [https://tools.ietf.org/html/rfc2231 RFC 2231] that is
encoded correctly. My MUA also displays it correctly, so it seems to be an
error with Google and Zimbra.
