• Halloween is coming! To celebrate the occasion, we dusted off a couple of old skins, and even created a brand new one (Pixel).
    To get into the festive spirit, install the Skins extension.
  • The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • The Plesk Mobile apps for iOS and Android and the Plesk Mobile Center extension have been deprecated, and are no longer available for new installations. In Plesk Obsidian 18.0.84, the Plesk Mobile Center extension will be removed from servers during the upgrade, and the Plesk Mobile apps will lose their server management features.
  • The Social Login extension has been deprecated and will be removed in Plesk Obsidian 18.0.84. After that, it will no longer be possible to log in to Plesk with a Google, Facebook, GitHub account, or with a passkey. Plesk usernames and passwords, as well as logging in with a WebPros Account, are not affected.

Plesk Mail Relay setting?

Right now I have mail relay set to "Authorization is required"
(SMTP is checked)..

I am getting email warnings where the sender is an address on my server where the domain exists, but the user doesn't.. which leads me to believe someone is using me as a relay spam sender..

How can shut this capcity down.. if set relay to "Closed" - The ability of my own web pages to send mail is also turn off..

Will the Blacklist setting help?

Thanks.
 
It doen't necessary mean that if a message is send from one of your mailadresses, that it is actually send from your server. You have to check the headers of the e-mail for that (in Outlook you find the headers by opening the message in a new window and go to view - options in the menu).

If the messages are send from your server, making it a closed relay is an option. However this also means that users that send mail from your server (for example from a website using CDOSYS or CDONTS or webmail) can't send message to external addresses.
