Add domain reputation based spam protection lookup in server-wide mail settings.
Add domain reputation based spam protection lookup such as the feed from dbl.dq.spamhaus.net, in addition to the existing IP DNSBL.
RAS shared this idea
The feature request is asking to protect recipients from spam by a domain reputation based lookup. However, this is already available by simply adding a suitable DNSBL like Senderscore to the DNSBL settings. Other solutions would require Plesk to operate their own DNSBL service, but that is not the task of a control panel.
