Webmail Subdomain Not Working

[C4talyst]

Hello,

I have a cPanel server that was brought online a few months ago. The thing has worked rathr flawlessly and today I added our first web site that's using a dedicated ip. The site resolves to the dedicated ip just fine and all the necessary DNS records are in place, however, the webmail.example.com subdomain does not work. When you try to hit that page in a browser, it takes you to the homepage of the site.

Any ideas?

Check that these three settings are checked in WHM > Tweak Settings

Add proxy VirtualHost to httpd.conf to automatically redirect unconfigured cpanel, webmail, webdisk and whm subdomains to the correct port (requires mod_rewrite and mod_proxy)

Automatically create cpanel, webmail, webdisk and whm proxy subdomain DNS entries for new accounts. When this is initially enabled it will add appropriate proxy subdomain DNS entries to all existing accounts. (Use /scripts/proxydomains to reconfigure the DNS entries manually)

Allow users to create cpanel, webmail, webdisk and whm subdomains that override automatically generated proxy subdomains
