Perhaps "lmtp -o smtputf8_enable=no" in master.cf can avoid
some of these delivery errors.

What will this trigger?
An earlier bounce at smtp delivery time?
Or a conversion to non-utf8 before sending it further into the system?
Or??
Pro / con for doing this change?
I tried google, but it just made me understand less.
