class IdnAddressEncoder

An IDN email address encoder.

Encodes the domain part of an address using IDN. This is compatible will all SMTP servers.

Note: It leaves the local part as is. In case there are non-ASCII characters in the local part then it depends on the SMTP Server if this is supported.
