Lines that look like,
UTF8SMTP :10024 /var/...: <sender@example.net> -> <rcpt@example.com>
BODY=8BITMIME SMTPUTF8 Received: from mx.example.com ([127.0.0.1]) by...
were previously unmatched because of the relatively-new "UTF8SMTP".
Similar lines that have "ESMTP" instead of "UTF8SMTP" are already
ignored, so it makes sense to ignore the "UTF8SMTP" lines too.
