I use the latest WAMP and I get this when I try to send emails:

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 C:\wamp\www\main\createaccount.php on line 8

Message delivery failed...

The message:

$to = "xxx@hotmail.com";
$subject = "Hi!";
$body = "Hi,\n\nHow are you?";
if (mail($to, $subject, $body)) {
  echo("<p>Message successfully se开发者_Python百科nt!</p>");
 } else {
  echo("<p>Message delivery failed...</p>");
 }

Do you need do download a "mailserver" also?

Please help.

This works for me and should work for you: Use Fake Sendmail and a webhost mail server (i.e. - Godaddy, 1and1, etc.).

1.) Download the sendmail zip and extract it to C:\Wamp\bin\sendmail (for purposes of this example).

2.) Edit C:\wamp\bin\sendmail\sendmail.ini and set the following to your mail server's requirements (mine are below):

smtp_server=mail.yourdomain.com
smtp_port=26
smtp_ssl=none
;default_domain=yourdomain.com
auth_username=smtpuser@yourdomain.com
auth_password=smtppassword
;pop3_server=
;pop3_username=
;pop3_password=
;force_sender=
;force_recipient=

3.) Set the path of sendmail.exe in your php.ini file.

[mail function]
; For Win32 only.
SMTP =

; For Win32 only.
sendmail_from =

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
sendmail_path = "C:\wamp\bin\sendmail\sendmail.exe -t"

4.) Restart Wampserver.

You might have success using Gmail, but there are a few extra tweaks to make it work. I prefer using the mail server of the webhost where I upload my code.

You are not running an smtp server on your machine, but you don't have to. Just set SMTP to a open smtp server for example:

ini_set('SMTP', 'smtp.yourisp.com');

Take a look at your ISP's home page or http://www.e-eeasy.com/SMTPServerList.aspx for list of SMTP servers.

If you have a desktop mail program, you can use the same address as you use for outgoing mail.

I think your mail server (SMTP) outgoing mail server is not configured in your php.ini file.

Have a look at this:

http://email.about.com/od/emailprogrammingtips/qt/Configure_PHP_to_Use_a_Remote_SMTP_Server_for_Sending_Mail.htm

Also hotmail doesn't allow you to use their mailservers. You should use yahoo or gmail.

Are you sure these servers have a mail program installed on them? If not, that's your problem. For example, XAMPP comes with a mail program called Mercury which you must start before you can send mail through the server.

Follow this article, it works if you have a gmail account. or at least any email account in which you know the server, port and this stuff.

Send Email From localhost

here is another solution - WAMP send Mail using SMTP localhost

KEEP IN MIND, everytime, after You change php.ini,

you must restart wamp (! ! !)

p.s. in php.ini, i have used:

SMTP = localhost 
smtp_port = 25 
sendmail_from = your_user@gmail.com

or if oyu cant edit php.ini, try to insert these lines in your php script.

ini_set("SMTP", "localhost");
ini_set("smtp_port", "25");
ini_set("sendmail_from", "your_user@gmail.com");
