And you can test is and send mail from here;

dont work;

I suggest your method using http://www.mail-maniac.com/index.php?page=formbuilder,

But I use this:
http://www.aeoncube.com/download/index.php?dlid=15
simple as hell to set up and customize with basic html knowledge; php coding not needed. free; fast; no relying on other sites- try it.

Or Matt's Formmail (cgi) or Jack's Formmail (php)

If you're working with PHP, I would suggest Jack's Formmail. It's just a modification of Matt's Formmail, which was written in CGI. I use it all the time and it works. Very easy to set up as well.

Thank you for your suggestions! I searched on google for scripts and hosted solutions and the best so far seems to be www.emailmeform.com , as they offer for free a lot of features that most other offer in paid memberships ( including Captcha's , unlimited forms and submissions, autoreply and statistics! ) .. So, I will go and try them out.
