Question
How to block a particular mailbox or a range of mailboxes belonged to a specific domain from sending emails to Plesk server?
Answer
Note: in order to block the email sender by IP, navigate to this article: Is there any way to block an IP address in Plesk Firewall?
-
Go to Plesk > Tools & Settings > Spam Filter > Black List.
-
Press the Add Addresses button.
-
Specify a particular mailbox or a range of mailboxes belonged to a specific domain in the Email addresses field, e.g.:
CONFIG_TEXT: johndoe@example.com
*@example.org
*@*.net -
Press the OK button.
Note: The steps above will add the address to individual black list, which will give it a score 100, making it be detected and processed as spam.
What to do with such messages can be only achieved on a mailbox level with the option "What to do with messages classified as spam" at Domains > example.com > Email Addresses > john.doe@example.com > Spam Filter tab.
In order to not receive messages added to blacklist select option "Delete all spam messages"
Note: SpamAssassin has to be installed on the server and enabled on the required mailbox.
-
Go to Plesk > Domains > example.com > Email Addresses > john.doe@example.com > Spam filter.
-
Click the Show Advanced Settings link.
-
Specify a particular mailbox or a range of mailboxes belonged to a specific domain in the Black list field, e.g.:
CONFIG_TEXT: johndoe@example.com
*@example.org
*@*.net -
Press the OK button.
Note: The steps above will add the address to individual black list, which will give it a score 100, making it be detected and processed as spam. Now, in order to effectively delete the messages detected as spam, click on "What to do with messages classified as spam" option on the same tab and select the option "Delete all spam messages"

Having tried the server wide option, I found the emails still appearing in the spam folder.
@John Bertin,
Hi! Such behavior is expected because when you add a mailbox to Black List, mail from that mailbox will be sent to Spam Folder.
You may use the solution from the Note in Server-wide section to delete all spam messages (this should be configured per mailbox).
