Answer

The spamassassin utility is used to manage Spamassassin spam filter through CLI:

Linux:

/usr/local/psa/bin/spamassassin --help

Windows:

"%plesk_cli%\\spamassassin.exe" --help

By using this utility, the following tasks can be performed on a Linux server:

• enabling/disabling server-wide spam filtering
• setting the criteria for automatic labeling of incoming messages as spam
• enabling/disabling use of mail-name specific spam filtering criteria
• adding mail messages to the Spamassassin's black and white lists
• marking mail subjects as spam
• deleting spam automatically
• inserting custom text into spam message subject lines automatically

And on Windows server:

• enabling the use of server-wide spam filtering settings
• setting the number of hits required to mark a letter as spam
• adding mail addresses to black and white lists
• marking mail subject as spam, deleting spam messages
