Hello pcready.cl,
Thank you for your post.
Our development team is aware of the following reported warning message in the exim edit window:
"Warning! directive_matcher could not parse error (date and time) cwd= /usr/local/cpanel/whostmgr/docroot 4 args: /usr/sbin/exim -bv -C /etc/exim.conf.test.work.02c269d3
(date and time) Exim configuration error: new_router "virtual_user" not found for "magicspam_virtual_user_spam"
router."
and this warning can be safely ignored for now.
If you search in your web browser (ctrl + f) on the "Exim Configuration Manager > Advanced Editor" page for "virtual_user:", you should see that the "virtual_user" router exists.
Please note that the warning exists only on the interface and can be safely ignored as long as the exim service is running.
Furthermore, this issue is being investigated by the cPanel team and you can find more information in cPanel forum thread:

Please let us know if you have any further questions.
