Why does the Return-Path include [email protected]?

Question

PHP

I send mail from the server, with the help of the mail() function and a small script, the script contains [email protected] when the letter arrives in the headers [email protected]

spf=fail (google.com: domain of [email protected] does not designate 193.124.176.128 as permitted sender) [email protected]
Return-Path: <[email protected]>

I'm in charge of where this email comes from. Because of it, letters end up in spam, because it does not match the sending domain, I don’t indicate it anywhere, hosting is also out of business.

Answer 1

Because you have ISPmanager and PHP in CGI mode. Go to the user level and select the PHP item in the left menu. There you can edit the value.

1. One site - one user. To be able to properly resolve CGI settings.
   
2. To enable domain mixing, add a line to /usr/local/mgr5/etc/ispmgr.confOption InsecureDomain and restart the panel.
