php generated confirmation email

[robertlob]

environment: Mac G4, Mac OS X Server 10.2.x,

My php code is supposed to auto generate a confirmation email to customers in response to some action they have taken.

The problem is, it will only send the confirmation email to users who have an account on my Mac OS X Server; it rejects messages to customers in other domains.

The mail server is configured to reject open relays, but users can send email to the outside world by authenticating. This works fine using an email client such as Outlook Express.

Since the email message is generated on the server (localhost), by a "user" with an account on the server, I assumed it should go.

I suspect that I need to authenticate in the php code, but I can find no information on how to do that.

php Code snippit:

$to = "$sender_email";    //to the customer
$subject = "Gallery Listing";
$mailheaders = "From: Trader's Bend Photo Gallery <[e-mail]> \n";
$mailheaders .="Reply-To: [email][e-mail][/email]\n\n";
mail($to, $subject, $msg, $mailheaders);

The above works fine as long as the $to address is in the tradersbend.com domain, but the it is rejected if the customer is in another domain.

[e-mail] is the sender and has an account on the server, but is not being recognized here.

What am I missing...

Thanks,

Robert <[e-mail]>

What is the server environment? My guess is that it lives on your personal computer which is connected to the internet via an ISP that is blocking port 25 (the smtp port).

Thanks for responding.

Server is a Mac G4 with Mac OS X 10.2.x system. It is co-located at my ISP's office with a static IP address and registered domain name. It is running php, Apache, and AppleMail.

From my laptop at home, I can create mail in Outlook Express using one of the accounts that is supposed to be used generating the php auto response mail. It goes through the server fine to any address I choose to send it; but when the php page creates the mail, it won't leave the domain. I get a "We do not Relay" message from AppleMail.

It appears to be an authentication problem to me, but I don't know the syntax to authenticate in php code when creating and sending an auto response.

Any ideas?

Robert

On your remote server, you should not have this problem. On your home server, your home ISP is blocking the email as non-authenticated. There is no workaround other than changing the ports on your home computer to one that the ISP isn't blocking.
