从php代码发送电子邮件

I want to send an e-mail using a php code,I am using wampserver.

an error appear :

 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 C:\wamp\www\Newsletter1\index.php on line 29

My file php.ini

[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = localhost
; http://php.net/smtp-port
smtp_port = 25

; For Win32 only.
; http://php.net/sendmail-from
sendmail_from = myEmail@gmail.com

Is there any more configuration to do?

Update

I'am using the mail function to send a newsletter to subscriber and I am testing now locally then I will test the code on production environment

You need a SMTP mailserver daemon running on localhost. If you are using a unix host and you don't want to setup a full SMTP agent, try removing the SMTP config part, thus directly using sendmail. From the docs:

The Windows implementation of mail() differs in many ways from the Unix implementation. First, it doesn't use a local binary for composing messages but only operates on direct sockets which means a MTA is needed listening on a network socket (which can either on the localhost or a remote machine).

If you are working on a test environement look at this link: http://www.toolheap.com/test-mail-server-tool/

This little app will simulate an SMTP server on your computer.

It gives you some hint on how to test and debug mail features for your php applications.

Check your Firewall maybe php is blocked to connect server. Or try change localhost to 127.0.0.1 .

You need either smtp server on your server or you need to connect to external smtp server to send email.

to connect via external smtp you can use

http://pear.php.net/package/Mail

here is answer to your question as well with an example of how to use it.
