Hi all, I have a terribly frustrating issue I'm trying to solve and wondered if anyone would be able to help?

I have a simple HTML / CSS website hosted on my webserver. This website has a basic web contact form that allows a user to fill in their details and click submit. It then sends an email to a single contact so they can then get in touch with the user.

This contact form is handled by a version of Formmail.php - Sadly I know very little about PHP, but from what I can gather I don't need to know much for this to work.

The issue I have is fairly individual. The email address that the form is sent to when submitted is located on a mailserver belonging to an ISP where they seem to have fairly stringent DNS checks. Submitting the form to this specific email address fails and logs the following error on local SMTP servers debug log (I am using MailEnable Standard Edition as my mailserver FYI):

09/21/12 11:44:52 ME-I0107: [828] Relay Granted: Sender IP (127.0.0.1) is within an authorized IP range.

If I change the address the form is sent to in the HTML and Formmail.php (for example to my own email address) it works absolutly fine - no problem. It seems to only give DNS errors when sending to my clients email address.

Formmail.php appears to use the "From" email address field submitted with the form as the email address that the form submission email is sent from. Checking the SMTP logs on the email server it appears that this isn't the case, the mail server we are sending to thinks that we are sending from "[SMTP:admin@localhost]". Because of this it is rejecting the email./

Looking at the SMTP logs we can see that it fails (above) sending to "easynet.net" and is successful (below) sending to "gmail.com".

So, in short, Formmail.php cannot appear to send an email via a form submission to my clients email address because it uses "admin@localhost" as a SMTP email address because the mail server rejects "localhost" in DNS. Other domains I've used in test appear to work no problem, so it isn't a specific problem with Formmail.php, I just need to know how to change Formmail.php so I can force the "From" ([SMTP:admin@localhost]) address to be something specific, and therefore stop getting rejected by "easynet.net"'s mailsevers.

Would anyone please be able to help me with this?

I am not familiar with FormMail but maybe this link helps:

http://www.scriptarchive.com/readme/formmail.html#email

In line 215 it uses PHP's internal mail function to send mail. There it sets in additional headers the From: addres using $post['email'] which some server reuire (I guess). But I think PHP's mail function sends mail using sendmail and not SMTP so maybe somewhere there could also be the cause for a trouble (well, eventualy sendmail goes to SMTP anyway).
