How to change 'from' field in Plesk email notifications sent to clients?

Question

Plesk email notifications sent to clients contain the personal email of the Administrator. How to change the 'From' field to hide this personal email address?

Answer

Warning: The solution below works only if Postfix/Qmail is installed on the server and is not relevant for MSMTP (relay only)

Plesk administrator can specify a custom email address to be used as a mail relay. The email address will be used as the sender address for all Plesk email notifications enabled in the Tools & Settings > Notifications menu.

To adjust the settings, perform the following:

1. Log into Plesk.

2. Edit the Plesk panel.ini file by adding the lines below there:

   CONFIG_TEXT: [notification]
   senderAddress=<custom email address>

   For example:
   

Note: Some notifications such as Additional Administrators activation email, password reset requests, etc. are sent from the "System" with the address: no-reply@<full-server-hostname>. To change this "System" sender email address set the required full hostname under Tools & Settings > Server Settings > Full hostname.
