I am using the following code to allow a user to submit an e-mail form to a specified address. The code works fine, however, the mail is being rejected with the following error:

553 5.1.8 <apache@atsomehost.com>... Domain of sender address apache@atsomehost.com does not exist (in reply to MAIL FROM command))

Using the code below, how do instruct PHP to send e-mail from a valid e-mail account/domain?

$ipi = getenv("REMOTE_ADDR");

Thank you

This problem happens often with shared hosting. I would check the DNS configuration of your server at: http://www.dnsstuff.com/ for mistakes.

Otherwise you should move to SMTP verified mail sending. There are a lot of classes out there than you can easily incorporate into your script.

Mail() uses sendmail by default and causes issues like this because of spamming exploits in the past.

Code wise the only change i would make is in your headers.

From: $visitor ($visitormail)

to

From: $visitormail

Apache and Postfix reside on the same server. The SMTP service works properly and is able to send e-mail to anyone.

When the form is submitted its sent as apache@gp2.hostname.com

I would like it to be sent from apache@hostname.com

Can this be done?

what SMTP server are you using in the php config?

If you are running on windows you can have multiple SMTP services (sendmail / exim etc.)

Verify that the default SMTP server is configured with inline options in your php.ini

I believe it is SMTP_path

for exim mine is set to /usr/sbin/exim -t as -t -d would make it wait for more information and hang.

by default php is configured for sendmail.
