The Watchdog notifications receive from the incorrect email address

Symptoms

• The Sender`s email address for the Watchdog extension is set as [email protected] in Plesk > Extensions > My Extensions > Watchdog > Open > Preferences.
• The rkhunter (Watchdog component) sends mail notifications from [email protected] email address(where the testdomain.tld is the server hostname):
  

Cause

This is a Plesk bug with ID #PPPM-7575, which will be fixed in the next Plesk update releases. 

Resolution

Until the bug will be fixed, apply the following workaround: 

1. Log into the server via SSH.

2. Using the vi text editor open the /usr/local/psa/admin/sbin/modules/watchdog/rkhunter file.

3. To set the [email protected].net email as a sender address for rkhunter,  find and change the line below from:

   MAIL_FROM="[email protected]${HOST_NAME_FULL}"

   To

   MAIL_FROM="[email protected]"

4. Save the changes.

   Note: such customization can be overwritten by Plesk updates.
