2，调用示例及说明 1），获得邮件列表

$mailList = array();
$mail = new jbxue_Email();
$connect = $mail->mailConnect($this->_imapServer,$this->_port,$this->_email,$this->_password,$this->_floder,$this->_ssl);
if($connect) {
    $totalCount = $mail->mailTotalCount();
    for ($i = $totalCount; $i > 0 ; $i --) {
$mailList[] = $mail->mailHeader($i);
    }
    $mail->closeMail();
}

2），获得邮件正文

$mailId = $this->getRequest()->getParam('id');
$mailHeader = array();
$mailAttach = array();
$mailBody = '';
$mail = new jbxue_Email();
$connect = $mail->mailConnect($this->_imapServer,$this->_port,$this->_email,$this->_password,$this->_floder,$this->_ssl);
if($connect) {
    $mailHeader = $mail->mailHeader($mailId);
    if($mailHeader['seen'] == 'U') {
$mail->mailRead($mailId);
    }
    $mailBody = $mail->getBody($mailId);
    $mailAttach = $mail->getAttach($mailId,$this->_attachPath);
    $mail->closeMail();
}

3），下载附件

$id = $this->getRequest()->getParam('id');
$name = $this->getRequest()->getParam('name');
$email = new jbxue_Email();
$email->getAttachData($id,$this->_attachPath,$name);
