using PHP to send mail, you can use Phpmailer. Phpmailer is a PHP function pack for sending e-mail so how does Phpmailer work? The first step, of course, is to download the Phpmailer package, which has two versions, a PHP4 version, and PHP5/6 version of the download after the appropriate download, see there are many files, in fact, most of them do not use and then enter the test to see Testemail.php file Here is an example code similar to<?PHP/** * Example script using Phpmailer with exceptions enabled* @package phpmailer* @version $Id $*/require‘.. /class.phpmailer.php ';Try {$mail=NewPhpmailer (true);//New instance, with exceptions enabled$body=file_get_contents(' contents.html ');//What to send$body=Preg_replace(‘/\\\\/‘,‘‘,$body);//Strip Backslashes$mail-&GT;ISSMTP ();//Tell the class to use SMTP$mail->smtpauth =true;//Enable SMTP authentication$mail->port = 25;//set the SMTP server port$mail->host = "smtp.163.com";//SMTP Server$mail->username = "[email protected]";//SMTP Server username$mail->password = "*********";//fill in your own email password//$mail->issendmail ();//Tell the class to use Sendmail$mail->addreplyto ("[Email protected]", "First Last");$mail->from = "[email protected]";//Sender Mailbox$mail->fromname = "small white";//Sender$to= "[Email protected]";//Recipient$mail->addaddress ($to);$mail->subject = "First Phpmailer Message";$mail->altbody = "To view the message, please UseAn HTML compatible email viewer! ";//optional, comment out and test$mail->wordwrap = n;//Set word wrap$mail->msghtml ($body);$mail->ishtml (TRUE);//Send As HTML$mail->send (); Echo ' Message has been sent. '; catch (Phpmailerexception$e) {echo$e->errormessage ();}? > The above code, there is note that the comparison of the important need to carefully fill out the SMTP server can refer to the WordPress send a workaround This article note: 1. If error: Could not execute:/var/qmail/bin/ SendMail then you need to put the configuration file in the$mail->issendmail (); Comment out 2. If you're using a space error: SMTP error:could not connect to SMTP host then you need to modify the class.smtp.php$this->smtp_conn = @fsockopen instead$this->smtp_conn = @pfsockopen because there is a lot of space to disable Fsockopen! Follow the above steps, your mail should have been sent successfully in fact Phpmailer package we really use the files only class.phpmailer.php and class.smtp.php
