George, Had this problem a year ago, although I'm not using PEAR. Have a look at http://ca3.php.net/manual/en/function.mail.php and this down in the additional_parameters(optional) section: "For example, this can be used to set the envelope sender address when using sendmail with the *-f* sendmail option." It is not well documented, don't know if this helps, but it may get you started.
