If the message was accepted with smtputf8_enable=yes, then it would
also have been accepted with smtputf8_enable=no or with Postfix 2.x.
The smtputf8_enable setting changes logging output. With
smtputf8_enable=no or with Postfix 2.x, all non-ASCII is logged as
"?". With smtputf8_enable=yes, UTF8 text is logged unchanged, but
other text is still logged as "?".
