* An ESMTP handler for SMTPUTF8 support (RFC 6531).

* SMTPUTF8 is required when sending to email addresses containing non-ASCII
* characters in local-part (the substring before @). This handler should be
* used together with Swift_AddressEncoder_Utf8AddressEncoder.
*
* SMTPUTF8 mode is enabled unconditionally, even when sending to ASCII-only
* addresses, so it should only be used with an outbound SMTP server that will
* deliver ASCII-only messages even if the next hop does not support SMTPUTF8.
