How can the php.ini file be modified to change the Postmaster email address?

To change the Postmaster email address in the php.ini file, you need to locate the "sendmail_from" directive and update it with the desired email address. This directive specifies the email address that will be used as the sender for emails sent by PHP scripts. Once you have updated the "sendmail_from" directive with the new email address, save the php.ini file and restart your web server for the changes to take effect.
