For some reason, cPanel thinks that mail.* is a domain alias for your main website: to be honest, I'm not sure how to fix this from within cPanel: but I know it could be fixed via root access via WHM/SSH: do you have access to either of those?
In the interim, I would recommend putting in a .htaccess redirect file such as:
Code:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond "%{HTTP_HOST}" "!^www\.arabwindow\.net" [NC]
RewriteCond "%{HTTP_HOST}" "!^$"
RewriteRule "^/?(.*)" "https://www.arabwindow.net/$1" [L,R,NE]
</IfModule>
which will redirect any and all requests that hit your website which are NOT going to https:// www. arabwindow.net to that domain name. Hope it helps!
