Warning: mail() [function.mail]: “sendmail_from” not set in PHP.ini or custom “from:”

Before you can send emails with PHP, you must change some particular settings in the php.ini file.
After you did the changes and you collide with this error

(Warning: mail() [function.mail]: “sendmail_from” not set in php.ini or custom…..)

you must do the following:

Uncomment the following setting in this file (remove the semicolons at the beginning).

and change this setting to this for example (if localhost)

If this issue occurs on your production server, change the default from address according to your domain, so admin@domain.com

However, this is not necessary. If you don’t want or simply because you can’t change the php.ini file, you can send additional headers, including this one:

From: Nobody <email@domain.com>

Please visit the official PHP manual for more information.
