PHP利用imap收件箱的例子

$host = '{imap.mail.yahoo.com:993/ssl}';
$user = 'user@yahoo.com';
$pass = 'password';
$inbox = imap_open($host, $user, $pass);
$mailboxes = imap_list($inbox, $host, '*');
$mailboxes = str_replace($host, '', $mailboxes);
print_r($mailboxes);

结果：

Array
(
    [0] => Bulk Mail
    [1] => Draft
    [2] => Inbox
    [3] => Sent
    [4] => Trash
)

重新打开指定的目录：

imap_reopen($inbox, $host.'Bulk Mail');
$emails = imap_search($inbox,'ALL');
print_r($emails);

SMTP =  163mx02.mxmail.netease.com
sendmail_from = wusong@192.168.1.100

var_dump(mail('597417106@qq.com','from php mail function','very intresting'));

步骤:
0: 引入
1: 实例化
2: 配置属性
3: 调用发送

require('./PHPMailer/class.phpmailer.php');

$phpmailer = new PHPMailer();

/*
设置phpmailer发信用的方式
可用用win下mail()函数来发
可以用linux下sendmail,qmail组件来发
可以利用smtp协议登陆到某个账户上,来发

$phpmailer->Host = 'smtp.163.com';
$phpmailer->SMTPAuth = true;

//设置收信人

// 添加一个抄送
$phpmailer->AddCC('597417106@qq.com','Aseoe');

// 发信
