The APS Catalog has been deprecated and removed from all Plesk Obsidian versions. Applications already installed from the APS Catalog will continue working. However, Plesk will no longer provide support for APS applications.
Please be aware: with the Plesk Obsidian 18.0.78 release, the support for the ngx_pagespeed.so module will be deprecated and removed from the sw-nginx package.
I dont know if you can disable the page, but you can disable webmail on a per domain basis. It can be found in the domain under mail > mail preferences.
Edit: Also, you can remove the DNS record for "webmail" in that domain. That will prevent anyone from seeing a horde login page. (apache redirects urls starting with webmail.* to the horde login)
