  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

disable SMTP relay for one domain

Hello,

is it possible to block SMTP just for one domain?
We got several domains continuously sending spam using autentication and causing blacklistins of the whole server.

Is there a way to block only SMTP relaying for just one domain/account ?

Thanks in advance,
 
First I would point you to the postfix config stuff, you will learn a lot looking through these.
http://www.postfix.org/STANDARD_CONFIGURATION_README.html

Secondly, if this user is getting you on blacklists and sending out a bunch of spam then I would just boot them now, save you the grief for the few bucks your getting off them its not worth it.
Third, do not ever let users send mail unauthenticated - its a bad bad practice and really the only people who use or need that are spammers.
