Subject: smtp: Support the SMTPUTF8 extension in the MAIL command

Support the SMTPUTF8 extension when sending mailbox information in the
MAIL command (FROM and AUTH parameters). Non-ASCII domain names will
be ACE encoded, if IDN is supported, whilst non-ASCII characters in
the local address part are passed to the server.

Fixes #4828
