Form Processing Feature Details

The sending of unsolicited email is an ever increasing problem on the internet. Spam bots continually harvest email addresses posted across the world wide web. In addition relentless spammers, intent on filling your inbox with junk, set up systems to automatically submit web forms. Fortunately Mail My Form provides many useful features to both free and upgraded users to help keep spammers away!

Hide Your Email Address
With Mail My Form your email address is not shown anywhere on your form page, not even in your HTML code. There are many form processing systems that require you to have code like this on your form page:

<input type="hidden" name="recipient" value="your_email@yourdomain.com">

This makes it very easy for automated spam bots to harvet your email address. With Mail My Form your email address is not shown anywhere on your page and so is safe from harvesting.

Block IP Addresses
Getting spammed by the same users? Mail My Form allows you to block unlimited numbers of IP addresses, including partial IP ranges.

Advanced CAPTCHA System
Mail My Form offers one of the most advanced CAPTCHA systems available for any remotely hosted form system. CAPTCHA works on the basis that humans can read certain images, but automated computer systems cannot. If you enable CAPTCHA on your form a random number image will be displayed to your user like the ones below. Your user must then enter the correct number before they can submit your form. This can help dramatically reduce the number of spam submissions via your form.




SpamAssassin
Mail My Form integrates with SpamAssassin to allow you to powerfully filer spam. SpamAssassin is one of the most popular spam filtering services in the world; unlike other services it requires no external sign up and no API key, so you can enable it instantly on your Mail My Form account. We allow you to specify exact values for marking form submissions as spam, allowing unparalleled control of the SpamAssassin system. You can find out more by visiting the official SpamAssassin website.

Custom Regular Expression Validation
Like all professional form mail services, all Mail My Form validation is done server side for maximum effectiveness; even if your user has JavaScript disabled, they must still follow your validation rules before they can submit your form. We offer standard validation options for all users, such as email validation, checking a field contains just numbers or checking a field contains just letters. However, what if you want to validate something more specific such as a US social security number or a UK postal code? Now with Mail My Form you can! We are the first form service to allow you to specify your own POSIX regular expressions for field validation. You can now validate any field with absolutely any validation you require, allowing for unparalleled field validation control. You can find out more about POSIX regular expressions by visiting the Wikipedia guide to POSIX regular expressions..
