Q&A
Q. How can I ease the burden on my mail server?
A. Besides looking into packaged mailing list software, you can bypass the mail() function and talk directly to your SMTP server via a socket connection. Such an example is shown in the PHP manual for the fsockopen() function (http://www.php.net/fsockopen), as well as in other developer resource sites.
- Q. Where do bounced messages go?
A. As with any email (not just those sent in the manner described in this chapter), bounces go to whatever address you specify in your From: or Reply-to: mail headers.
