How do I get rid of the default page on "lists.domain.tld"

[_dk3880_]

When I enable mailing lists on a domain, Plesk automatically creates the "lists" subdomain for this domain.

Unfortunately, this subdomain shows up with Plesk's default page when users visit it directly, which is pretty far from a "whitelabel" solution and absolutely unwanted in this case ... (I'm setting this up for a corporate customer ...)

I would prefer to provide a custom page instead which links to the archive pages of all mailing lists, but that doesn't seem to work.

Plesk denies the manual creation of the "lists" subdomain (and so: its FTP space) once the first mailing list is defined, which might have been a workaround.

In short, is there a solution to define a start page for the "lists" subdomain that does NOT involve
- dirty hacks in the abcxyz config files
- a replacement of the Plesk skin?

Thanks.
