PHPMailer\PHPMailer

PHPMailer::mailPassthru() │ private │ WP 1.0

Call mail() in a safe_mode-aware fashion. Also, unless sendmail_path points to sendmail (or something that claims to be sendmail), don't pass params (not a perfect fix, but it will do).

Method of the class: PHPMailer{}

No Hooks.

Return

true|false.

Usage

// private - for code of main (parent) class only
$result = $this->mailPassthru( $to, $subject, $body, $header, $params );

To

$subject(string) (required)

Subject

$body(string) (required)

Message Body

$header(string) (required)

Additional Header(s)

$params(string|null) (required)
