Secure PHP contact form mailer (with multiple recipients and senders)

Hi Freelancers,

Due to recently having been confronted with serious issues from an insecure contact form on my customer's website where bots used it to send out tons of spam, I am now looking for someone who can provide me with a secure PHP contact form mailer that meets my requirements. Please have the time available to complete this task in one day.

In terms of security, I have no preference for the way in which spam/bots are blocked, but it should follow the latest best practices. Google's reCAPTCHA V3 might be an idea, but if there are alternatives that do not require 3rd party plugins that'd perhaps be even better? I will leave this up to you professionals.

In short, my requirements are:

- Should be secure without being obtrusive;

- Should allow for various recipients, senders and messages.

- Customizable, so I can easily edit and use the code for all my other customers' websites;

- Despite coming from a PHP form mailer, the sent messages should not be seen as spam.

How the form should behave ---------------------------------------------------------------

A) The form should have these fields, of which all fields are mandatory except for phone number:

* Name

* Phone number

* Email address

* Subject

* Message

B) On succesfull submit, the form should send three different messages to three different recipients, i.e. myself (as a BCC), my customer and the website user submitting the form.

1. Me: I want to only receive a message with the title of the form in the header, so no actual body content due to privacy reasons. For me it's just a matter of being able to keep track of how many messages were sent through a specific website and seeing the subject of the user submitted message to check the message relevancy.

- Header: Webform Customer A: [User subject]

- Body content: none

2. My customer: he should receive the entire content of the submitted form, i.e. name, email address, subject and message.

- Header: Webform Customer A: [User subject]

- Body content: everything user submitted, so their name, email, phone number, subject and message.

3. User who submits the form: should receive an automated message stating their message has been received and will be replied to asap. And below this message they will find a copy of their submitted form with all their details (name, email, phone, subject, message).

C) Different senders.

- I want my "empty" copy send to me from my customer's email address;

- The copy to my customer should be send from the website user's email address;

- The copy to the website user should be send from my customer's email address.

D) after a succesfull submit the user should be redirected to a "thank you" page. This I use to measure my customer's website conversions.

My current (flawed) contact form mailer ---------------------------------------------------------------

Attached you will find an example of how my current setup is regarding the page with the form ([login to view URL]) and the form mailer code ([login to view URL]). It works exactly as I want it to, except for the security element. This has just been attached for reference of course, you may do this assigment the way you think is best, but perhaps seeing it makes things a bit more clear than I can explain in words.

In my current contact form there was some sort of check that made sure the contact form was actually being send from the user being on my customers contact page ($valid_ref1 in the attachement) and not from some remote location. In addition, there was some sort of javascript calculation check that apparently bots couldn't do to try to prevent spam and an onclick event in the submit button. If you're interested, please examine the attached files.

I expect to be provided with an explanation of how your form prevents spam and clear instructions regarding the implementation. Which part to go where and which data to edit to suit my purpose, such as the various email adresses and the automated messages to be send.

Thanks!
