MIME::LITE 模块发送邮件需要什么额外配置
my $msg = MIME:Lite->new(
From =me@myhost.com',
To =taohaoran1024@163.com',
Subject =哈哈哈哈;,
Date =>"templa"
);
$msg->send( );

这样总是发不出去，我仅仅装拉MIME:Lite模块，难道还要求别的配置？

use MIME::Lite;----$.
use MIME::Lite;

$msg = MIME::Lite->new(From => 'xxxx@xxxx.xx',
To => 'xxxxx@xxxx.xx',
Subject => 'Test',
Type => 'multipart/mixed');
$msg->attach(Type => 'application/pdf',
Path => 'c:\cc_ref_2.pdf',
Filename => 'cc_ref_2.pdf');
$msg->send('smtp', '192.168.1.6');
