Comment 4 for bug 1862154

Sorry - mistyped when I said "reintroduced" - can confirm this is present in previous versions, as per upstream releases.

Steps to reproduce on a clean system -

# lsb_release

# sudo apt-get install spamassassin
# sudo service spamassassin start

Locate the attached email example on the system, then run spamc against it -

# spamc -R < /tmp/bug1862154.eml
# grep "domain is utf8 flagged" /var/log/mail.log
