程序中用到了php的mail函数，该函数定义如下：
bool mail ( string $to , string $subject , string $message [, string $additional_headers [, string $additional_parameters ]] )
如果邮件发送成功返回True，否则返回False
<html> <head> <title>Send email with CC and BCC</title> </head> <body> <form action="sendemail.php" method=post name=form1> <table> <tbody> <tr> <td> <div align=right><b>To</b></div></td> <td> <p>Name <input name=mailtoname size=35><br />E-mail <input name=mailtomail size=35></p></td></tr> <tr> <td> <div align=right><b>CC</b></div></td> <td><input name=mailcc size=35> </td></tr> <tr> <td> <div align=right><b>BCC</b></div></td> <td><input name=mailbcc size=35> </td></tr> <tr> <td> <div align=right><b>Priority</b></div></td> <td><select name=mailpriority> <option value=1>Highest</option> <option value=2>High</option> <option selected value=3>Normal</option> <option value=4>Low</option> <option value=5>Lowest</option> </select> </td></tr> <tr> <td><div align=right><b>Subject</b></div></td> <td><input name=mailsubject size=35></td></tr> <tr> <td> <div align=right><b>Message</b> </div></td> <td><textarea cols=50 name=mailbody rows=7></textarea></td></tr> <tr> <td colSpan=2> <div align=center> <input name=Submit type=submit value=Submit></div> </td> </tr> </tbody> </table> </form> </body> </html>
后端php代码，保存为sendmail.php
<html> <head> <title>Send Mail Script</title> </head> <body> <?php $message= " " ; if (empty ( $mailtoname) || empty ( $mailtomail) ) { die ( "Recipient is blank! ") ; }else{ $to = $mailtoname . " <" . $mailtomail . ">" ; } if ( empty ( $mailsubject) ) { $mailsubject=" "; } if (($mailpriority>0) && ($mailpriority<6)) { $mailheader = "X-Priority: ". $mailpriority ."\n"; } $mailheader.= "From: " . "Sales Team <sales@yourdomain.com>\n"; $mailheader.= "X-Sender: " . "support@yourdomain.com\n"; $mailheader.= "Return-Path: " . "support@yourdomain.com\n"; if (!empty($mailcc)) { $mailheader.= "Cc: " . $mailcc ."\n"; } if (!empty($mailbcc)) { $mailheader.= "Bcc: " . $mailbcc ."\n"; } if (empty($mailbody)) { $mailbody=" "; } $result = mail ($to, $mailsubject, $mailbody, $mailheader); echo "<center><b>Mail sent to ". "$to". "<br />"; echo $mailsubject. "<br />"; echo $mailbody. "<br />"; echo $mailheader. "<br />"; if ($result) { echo "<p><b>Email sent successfully!</b></p>"; }else{ echo "<p><b>Email could not be sent. </b></p>"; } ?> <div> <table><tr><td><div><b>To</b></div></td> <td><b> <?php echo $mailtoname . " [". $mailtomail . " ]";?> </b></td></tr> <tr><td><div><b>CC</b></div></td> <td><b><?php echo $mailcc;?></b></td></tr> <tr><td><div><b>BCC</b></div></td> <td><b><?php echo $mailbcc; ?></b></td></tr> <tr><td><div><b>Priority</b></div></td> <td><b><?php echo $mailpriority;?></b></td></tr> <tr><td><div><b>Subject </b></div></td> <td><b><?php echo $mailsubject;?></b></td></tr> <tr><td><div><b>Message</b></div></td> <td><b><?php echo $mailbody;?></b></td></tr> </table> </div> </body> </html>
