* <p>
* <strong>Caution</strong>

* Since 7.2.0 accepts an array. Its keys are the header names and its values are the respective header values.
* </p>
* <p>
* This is typically used to add extra headers (From, Cc, and Bcc).
* Multiple extra headers should be separated with a CRLF (\r\n).

* a From header. This can be set with the
* additional_headers parameter, or a default
* can be set in &php.ini;.
* </p>
* <p>
* Failing to do this will result in an error
* message similar to Warning: mail(): "sendmail_from" not
* set in php.ini or custom "From:" header missing.
* The From header sets also
* Return-Path under Windows.
* </p>
* <p>
* If messages are not received, try using a LF (\n) only.

* The additional_parameters parameter
* can be used to pass additional flags as command line options to the

* this can be used to set the envelope sender address when using
* sendmail with the -f sendmail option.
* </p>
* <p>
* The user that the webserver runs as should be added as a trusted user to the
* sendmail configuration to prevent a 'X-Warning' header from being added

* For sendmail users, this file is /etc/mail/trusted-users.
