Arbitrary mail headers can be set by using the addHeader()
method. It requires two
parameters containing the name and the value of the header field. A third optional parameter determines
if the header should have only one or multiple values:
Example 33.10. Adding E-Mail Message Headers
$mail = new Zend_Mail(); $mail->addHeader('X-MailGenerator', 'MyCoolApplication'); $mail->addHeader('X-greetingsTo', 'Mom', true); // multiple values $mail->addHeader('X-greetingsTo', 'Dad', true);
To set the Reply-To: header there exists the function setReplyTo($email, $name=null)
,
because it requires additional special escaping of the different parts (email and name).
