SPAM protection - Check if sender Mail domain exists
For better SPAM Protection it would be nice to add an Option to let the Mailserver check, whether senders Domain is existing or even not.
I got Mails from "Domain.xyz" wich is of Course no valid TLD.
"Reply-To" is of Course an valid Mail adress.
On request, my Data-Center told me they could activate that Option, but while Plesk is Controlling that config, on next Plesk update the Change gets lost.
So: Could you add in Plesk that Feature as an Option?
Thank you. As far as I remember this checking can be configured by spamassassin but anyway we will consider the possibility of implementing this feature in future Plesk releases.

Please add option in mail configuration, which deny send email, if sender not exist on server (E-mail not created manually).
This option help to stop sending spam from web-site (function mail() in php).
