Symptoms
The email message headers "X-Ham-Reports" and "X-Spam-Reports" are not readable due to encoding.
Description
We've opened an internal case for our development team to investigate this further. For reference, the case number is CPANEL-50170. Follow this article to receive an email notification when a solution is published in the product.
Workaround
If necessary you can disable the RFC2047 encoding via the following steps.
-
Make a backup of the "default_spam_scan" file:
mkdir -p /root/cptechs/
cp -a /usr/local/cpanel/etc/exim/acls/ACL_SPAM_SCAN_BLOCK/default_spam_scan /root/cptechs/ -
Remove the RFC2047 reference using sed:
sed -i 's|rfc2047:\${\(.*\)}|\1|' /usr/local/cpanel/etc/exim/acls/ACL_SPAM_SCAN_BLOCK/default_spam_scan -
Remove the headerwrap_130 reference using sed:
sed -i 's|\${headerwrap_130:\(.*\)}|\1|' /usr/local/cpanel/etc/exim/acls/ACL_SPAM_SCAN_BLOCK/default_spam_scan -
Rebuild the Exim configuration and restart the Exim service:
/scripts/buildeximconf && /scripts/restartsrv_exim
