[Apologies for the double post, I have already posted this question in the "PHP Coding Help" section, it was suggested to post it here in the "3rd Party PHP Scripts" section as well.]

 

Hi all, I am a total beginner at pretty much everything to do with Web development, but sadly especially beginner at PHP. I'm keen to learn though (even it if takes me a while to understand!).

 

I am trying to add a simple form to a webpage that allows a visitor to fill in their name, then their email address plus a couple of other fields and click on a "submit" button. This will then send a basic email with the users information to a set email address.

 

I've downloaded and installed "Formmail.php" into my website, I've created some inputs in the HTML, the HTML loads fine, I can see the form fields, but for the love of all things holy when I click "submit" I cannot get it to send email out.

 

I am totally ignorant at how PHP (or any other scripting language) works, and especially ignorant at how Formmail.php works. I cannot figure out where it is asking for any SMTP server to use to send email (is it even using one?), or how it is is sending email? I realise the error I'm getting is something to do with authentication, but can't see how to get it to authenticate properly? I have an SMTP server I can use (if needed), with authentication credentials ready - but as said above, ignorance of how this is supposed to work is playing a big part with my failures here.

 

The specific error I get when clicking on the "submit" button is this:

 

Warning: mail() [function.mail]: SMTP server response: 530 SMTP authentication is required. in D:\Websites\synergytraining.co.uk\formmail.php on line 224

There was an unknown error while sending email.

« go back

 

So I guess it cannot authenticate with the email address I want to send to? I'm unsure as to how to do this though. I have tried changing some of the User Config setting below to no avail - I'd really appreciate some kind soul to help me please.

 

Current Formmail.php code I have installed is below.

 

Kind regards in advance.
