First fill in the content in the above program in the file, such:
Var $ host = "smtp.sina.com.cn"; // host
Var $ port = "25"; // The port is generally 25
Var $ user = "users"; // SMTP-authenticated account
Var $ pass = "users123; // authentication password

Put this file under your website, as long as your website program accesses it ,.
Then you need to use the mail program to include such as: include ('smtp. class. php ');
Then use
$ Mails = new smtp_mail ();
If ($ mail-> send ("sender address", "recipient email address", "topic", "content ")){
Echo "sent successfully! ";
} Else {
Echo "the email server is busy. please try again later ";
}
