Validation Form is not working

Question

My validation contact form is not working. While I try to submit the form the following error occurs:

Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in E:\CMS_Site\wamp\www\sitename\contents\send_mail.php on line 53

Answer 1

Your code for sending mail through php has no issue at all. if you are using WAMP in windows ,their will not have any SMTP server setup. so if you need to send mail from WAMP you need to use any SMTP server support.You can use Mandrill Mailchimb to send Email from localhost by just create an a/c in it, download swift files and add it in your working directory to setup mail server.To read-more on how to send mail through mandrill see below code..

or

You can work this code in a live server which supports SMTP setup.
Sending Mail via Mandrill Swift files in your code.You can change message subject etc as your own.

Answer 2

WAMP does not have an SMTP server.

Explanation

To be able to send email you need an outgoing email server. In most Linux systems there exists one by default, and PHP will use sendmail, a Linux app for submitting mail to whichever mail transfer agent you have installed.

In Windows, to be able to send mail from PHP you need an outgoing mail server somewhere and you need to tell PHP the address and port of it. This is done in php.ini using the SMTP and smtp_port settings. It will default to 'localhost' on port 25. Unless you have set up a mail server on that machine, that will fail.

If your ISP gives you an outgoing mail server, for example, you could use its address and port number. Or, if you're serious about sending mail, you'd set up your own mail server on the local machine or someone in your local network.
