I was unable to send a successful test email, after updating to PHP 7.0.
Found a log in data/owncloud.log similar to:
{"reqId":"XXXXXXX","level":3,"time":"2018-02-19T02:56:55+00:00","remoteAddr":"8.8.8.8","user":"XXX","app":"PHP","method":"POST","url":"\/index.php\/settings\/admin\/mailtest","message":"Use of undefined constant INTL_IDNA_VARIANT_UTS46 - assumed 'INTL_IDNA_VARIANT_UTS46' at \/home\/user\/public_html\/owncloud\/lib\/private\/Mail\/Mailer.php#135"}
All my SMTP settings are correct. Has anyone else had this issue after updating from PHP 5.6 to PHP 7.0?
CentOS 6.9, PHP 7.0, WHM/cPanel with EA4
