How to test SpamAssassin, Kaskersky and DrWeb antiviruses?



To test SpamAssassin it is necessary to send a test email containing the following string of characters in message body (in upper case and with no spaces or line breaks):


Note: The test email can be sent from an account outside of your network.

While testing, note that Gtube test email gives +1000 scores to spam. So, even if a mailbox is in the whitelist, mail still will be detected as spam because whitelisted emails get -100 scores. Detailed information about what scores an email got can be found in email header. The output will look similar to:

    * -100 USER_IN_WHITELIST From: address is in the user's white-list
    * -1.0 ALL_TRUSTED Passed through trusted hosts only via SMTP
    * 1000 GTUBE BODY: Generic Test for Unsolicited Bulk Email
    *  0.0 TVD_SPACE_RATIO No description available.

To modify the maximum score that white- and blacklisted emails will get, modify /usr/share/spamassassin/ file and set the required score for USER_IN_BLACKLIST and USER_IN_WHITELIST parameters.


To test Kaspersky Antivirus, DrWeb or any other antivirus, attach a test file that contains this special string:


The file that already contains a special string can be downloaded from the Kaspersky Labs server:

Results can be seen in %plesk_dir%admin/logs/plesklog_avstat<date>.log file

Note: Plesk debug mode should be activated at HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\PLESK\PSA Config\Config` > debug(DWORD)=1
