為大家舉一個php使用smtp發送郵件的代碼，簡單實用，有需要的朋友，可以參考下。完整代碼如下。 '指令碼學堂', //這裡填寫網站名稱 );$mail = Array ( 'state' => 1, 'server' => 'smtp.abc.com', 'port' => 25, 'auth' => 1, 'username' => 'admin@abc.com', 'password' => '123456', 'charset' => 'gbk', 'mailfrom' => 'admin@abc.com' );function sendmail($mail_to, $mail_subject, $mail_message) { global $mail, $bfconfig; date_default_timezone_set('PRC'); $mail_subject = '=?'.$mail['charset'].'?B?'.base64_encode($mail_subject).'?='; $mail_message = chunk_split(base64_encode(preg_replace("/(^|(\r\n))(\.)/", "\1.\3", $mail_message))); $headers .= ""; $headers .= "MIME-Version:1.0\r\n"; $headers .= "Content-type:text/html\r\n"; $headers .= "Content-Transfer-Encoding: base64\r\n"; $headers .= "From: ".$bfconfig['sitename']."<".$mail['mailfrom'].">\r\n"; $headers .= "Date: ".date("r")."\r\n"; list($msec, $sec) = explode(" ", microtime()); $headers .= "Message-ID: <".date("YmdHis", $sec).".".($msec * 1000000).".".$mail['mailfrom'].">\r\n"; if(!$fp = fsockopen($mail['server'], $mail['port'], $errno, $errstr, 30)) { exit("CONNECT - Unable to connect to the SMTP server"); } stream_set_blocking($fp, true); $lastmessage = fgets($fp, 512); if(substr($lastmessage, 0, 3) != '220') { exit("CONNECT - ".$lastmessage); } fputs($fp, ($mail['auth'] ?
