Spam-free contact form?

[devilzfan300]

Is there a contact form that can protect again spam being sent through it? Also, one that does not require a link back would be good.

If there is none that exist, can I customize my own?

any answers yet? I still havent found one

themike dot com has one that is licensed under the gpl. The link is appreciated but I do not think it is required.

You can create your own template. It has visual captcha.

I know one form ver rodumentary but very efective.

Yo can do your form and add one more Text field hiding it. It will now be visible to your users but SPAM-ROBTS will fill all fields. So you have to check if this fomr have information in this field or not to decide if its SPAM.

Spam bots take advantage of the fact that many contact forms are vulnerable to Email header injection. When you receive spam from your contact form, the same spam was just sent as blind carbon copies to another 10 or 20 people from your mail server. Captcha can help keep the bots from using your form, but you also need a script that is safe against injection.

How do I find a script that is safe from injection and how do I know it is really safe against injection?

I also want to figure out how to check the following:

- From address is filled out
- From address is a conformant e-mail address
- From address does NOT contain my own domain name
- From address's domain exists (has a DNS MX record)
- Message has been entered

I will keep updating

So if you dont find a script you have to check a NULL fields.
