How to change mail address of the sender when using mail() function

[BonCev]

Now, when I send a mail with the function php mail(), the default sender adress is mydomaincom@mydomain.com

Where I can change it ?

I found the option "user" in
./php5/fpm/pool.d/mydomain.com.conf
user=mydomaincom

but it's wrtied do not modify this file because it is relied with plesk...

(I know I can use headers in my php function but it's not that i want)

Hi BonCev,

pls. consider to read the official PHP documentation for your question: http://php.net/manual/de/mail.configuration.php
Have a closer look at "sendmail_from" and "sendmail_path".

With Plesk, you are able to add custom PHP settings for each service-plan, subscription, (sub)domain, or you are able to define server-wide settings. Please read and follow:

Customizing PHP Configuration ( Plesk online documentation for Plesk 12.5 )​
