ANTI SPAM MAIL FORMS A must for every web site, that wants to receive messages from its visitors!
It is not very difficult to prevent spammer-hackers infiltrating your web site. However, most mail forms and anti-spam software that are offered on the web, do not give you that protection. Nowadays, if you have any e-mail addresses on your web site, spider robots will harvest them and send spam mail to those addresses. Instead, you can use mail forms, that contain no e-mail addresses. These mail forms send the user info to a processing page (that I make in PHP coding) and that code cannot be copied by any hacker, nor infiltrated by any spider robot.
The mail form itself can not give you any protection, because hackers can copy and modify it, to send you spam and even to others, by so called e-mail injection. Only the processing page, that they have to send their spam to, can stop them. When you read an anti spam mail form offer and it says that it prevents spider robots from using it, that is not enough. Spider robots are the least harmful. Much more nasty are the hackers, humans, not dumb robots, who have various tricks to get around any measure taken in mail forms. Only the processing page can stop them.
This processing page can do more than just preventing you to get spam. It can also prevent that your mail form is used to send spam to others, which my scripts do. It can even report the spam source to infected computers, usually ISP servers. Hackers upload there scripts, being modified copies of mail forms, with a so called trojan to ISP servers, or can place them on your, or any computer, with so called zombies. There is no sure way to prevent them doing that. However, by reporting every time these zombies and Trojans send spam, the ISP servers can trace and remove the trojans - this causes the hackers a lot of extra work. The processing pages I make can do this reporting automatically, if you wish. In this way you can not only protect yourself, but also fight back against the spammer-hackers, attacking and abusing your site.
A simple mail form form looks something like this:
To contact me, please fill out the form below
Your name:
Your e-mail address:
Subject:
Your message:
It can of course be much larger, with may more fields to fill in, like submitting an address, telephone/fax, etc, anything you want. It can send the info to any number of recipients you want.
It can be on a separate page, yes or no opening in a new window, or be imbedded in an existing page. After the form info is submitted, it goes to the processing page, that then comes up in any way you want and shows a thank-you message, or an error message, in case the submitted info was not done correctly. On error, it will not send the info to you and eventual other recipients.
(if you want to have hackers reported, no error message is displayed, so the hacker doesn't know he has failed and thus goes on exposing himself. But you will get a notification of each reporting event, so you now you are doing "good hunting")
If you would look at the source code of the processing page, you will only see what it displays on the screen. The processing code itself is invisible and can thus not be accessed by a hacker, who has only the mail form to work with. Also a spider robot cannot access the processing code and thus not extract any e-mail addresses from it.
You can however prevent a spider robot to use the mail form, by requiring the user to do something for the mail form to send the info to the processing page. This is useful if you want to use a form to let a user download something, or go to an e-commerce page and you want to send yourself a message that such has been done, not by a robot, but by a physical person. You can see examples on my site here
Indeed, you can use forms for other purposes than to receive written messages only. For such other purposes, where no messages have to be submitted, hackers usually are not interested in, so you only have to deal with spider robots then.
If you would be interested to let me make one or more anti spam mail forms for you,

The backgrounds of spam
You have of course noticed that all spam mails want you to buy something. Also if you receive web addresses only, the idea is that you click on them and get lured into a purchase. The source of all this spam are the so called affiliates, tens of millions of common people like you and me, who hope to get "rich" while sleeping. They have to do a lot of advertising to make any sales and they therefore hire "email-blasting" firms, that use spider robots and hackers to "blast" their spam over the web, hundreds of millions of spam mails every day. The irony is that these affiliates in fact never will make more than a few sales per month, whereas the affiliate providers, the selling web companies, see a tremendous increase of their sales from thousands of affiliate-slaves working for free for them - it's genius!
