Exim version 4.90devstart-1178-b07e68e5-XX #30 built 04-Sep-2019 14:24:55

(Although WHM tells me Exim version 4.91-3)

Trying to add a new custom filter for the first time after fairly recent exim updates. Getting this error when trying to save:

Error message from syntax check:
2019-09-10 08:46:48 Exim configuration error in line 100 of /etc/exim.conf.buildtest.work.9a690f71:
main option "smtputf8_advertise_hosts" unknown

The exact line this references:

smtputf8_advertise_hosts = :

A search for "smtputf8_advertise_hosts" didn't help... I'm stuck!

Hello @ksechrist,

It looks like you're using an end-of-life version of cPanel & WHM on this system. Can you confirm which version is installed? EX:

cat /usr/local/cpanel/version

This is particularly important due to the recent Exim vulnerability documented at:

CVE-2019-15846 Exim - cPanel Knowledge Base - cPanel Documentation

documentation.cpanel.net

You can read about our EOL policy and how to update cPanel & WHM on the documents below:

Thank you.
