  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.
  • 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.

Mail Relay/Spam

I am having problems where people are apparently using my mail server to send spam.. and the sender (reply addr) is a know address on my server.. so relay (auth required) is allowing it..

Any recommendations?
 
Open up the mail enable administrator go to Connectors, right click on SMTP and go to properties

Click to tab relay and make sure "Allow Local Sender Address" is unchecked.
 
If I do that, won't that turn off the ability for me to send legitimate mail from local senders?
 
No, those are set by IP for the server. Then for hosting clients (outlook) they use SMTP Authorize.
