The script we are recommending is Tectite Formmail - this shouldn’t be confused with other scripts with similar names. This particular script has been around for many years and has not exhibited any security vulnerabilities that we know of. You can download a free copy of the script from the link below.
Please Note: Ensure that your web hosting supports PHP before implementing this solution - most do, but some low price or free hosting services don’t.
The developer of the script does offer a configuration option for which they make a nominal charge. But, if you’re up to it, download the free script and make the relatively few minor edits yourself. After downloading, you will see a folder in your downloads folder named formmail. Inside the folder will be three files - the latest version of the script named formmail.php, a previous version with the name formmail(version number).php, and a sample HTML form.
The first thing you should do is make a copy of the formmmail.php file and give it a more meaningful name - for example ‘your-domain-mail.php’. You’re now all set to go and ready for making a few small edits to the script. For this you will need a plain text editor - you can use Apple’s Text Edit app for this. Just click on the script file, right-click and choose open with - then choose Text Edit from the context menu.
