    I see Austin was able to get you some good details about one of the Apache includes causing a conflict with the webmail redirect.

    @cPRex Hello, Yes indeed, support did find the problem in the custom configuration. There was inside an include file /etc/apache2/conf.d/userdata/std/2_4///.conf a rewrite rule for adding "www" to the domain name, [CODE=apacheconf] RedirectMatch 301 (.*) https://www.DOMAIN.TLD$1
    Due to the order of processing of Apache directives, the custom configuration was imposing on cPanel's default service subdomain configuration that resides in the same virtualhost block. This has been changed in [CODE=apacheconf] RedirectMatch 301 (.*) https://www.DOMAIN.TLD$1
    to avoid interference with the CPANEL proxy rules. In fact it was even an old rule for an alias domain that is not even present anymore, but was still present in the custom includes :-(. So the lesson is that a regular review of these custom Apache includes is useful to not let there old configuration includes ! Big thanks for the help to solve this ! Yves
