Mail from Wordpress

Hello,
I have a multiserver set up with ISPconfig 3.2.7p1
On my webserver I have a wordpress site. From it, I try send mail.
I use wpsmtp plugin: it sends mail via smtp authentication. I define my account [email protected].
I made a test sending a mail to [email protected]
My webserver is connecting to my mail server. But instead of using user defined in wpsmtp pluging ([email protected]), it used "[email protected]"
See mail.log from my mailserver

Code:

I did #grep -r "webmaster@" /*
it gives

Code:

etc/php/7.4/fpm/pool.d/web6.conf:php_admin_value[sendmail_path] = "/usr/sbin/sendmail -t -i -f [email protected]"
etc/apache2/sites-available/dom.tld.vhost:          ServerAdmin [email protected]

I try to find where [email protected] is defined inside ISPConfig. I use hostmaster instead of webmaster, I would like to change ServerAdmin.

I have another question: when wordpress is sending a mail via wp_mail(), it seems wordpress uses etc/php/7.4/fpm/pool.d/web6.conf ? Where should I look to understand why wpsmtp settings are not used?

 

thanks a lot

I would like to change [email protected] into [email protected] in my vhost, is there a setting inside ISPC ?
should I use sed command ?

 

I read ServerAdmin directive is deprecated.
is that correct ?
