I am trying to find out how to set the envelope sender address with the Pear mail_queue system:
With the regular PHP mail command you can define that with the -f option:
mail('firstname.lastname@example.org', 'Subject', 'Body', 'From: email@example.com', '-f firstname.lastname@example.org');
But i have no idea how to define that with Pear mail_queue.
Any ideas are very welcome!
Thank you in advance.
