小弟目的想在嵌入式开发板上实现接收邮件，当然谷歌了一下，发现还是有很多实现方法的：php最简单，C socket实现效率最高(我是这么感觉)，当然也少不了python实现(不过还没动手测试)等等。

今天先介绍一下php 接受邮件类，这个类最初是老外Mitul Koradia写的，感觉实现功能也很完整：

该类的主要方法如下：

class receiveMail

{

...

function receiveMail($username,$password,$EmailAddress,$mailserver='localhost',$servertype='pop',$port='110',$ssl = false) //Constructure

function getHeaders($mid) // Get Header info

function getTotalMails() //Get Total Number off Unread Email In Mailbox

function getUnreadMails() //Get Number of Unread Mail from Mailbox

function searchUnreadMails() //Find Numbers of Unread Mail by imap_search Method

function GetAttach($mid,$path) // Get Atteced File from Mail

function getBody($mid) // Get Message Body

function deleteMails($mid) // Delete That Mail

function close_mailbox() //Close Mail Box

不过有些瑕疵，我阅读后稍作修改，主要是邮件头没进行MIME解码，邮件中文内容乱码。

首先关于邮件头的解码过程，Mitul Koradia的处理方法如下：

function getHeaders($mid) // Get Header info

{

if(!$this->marubox)

return false;

$mail_header=imap_header($this->marubox,$mid);

$sender=$mail_header->from[0];

$sender_replyto=$mail_header->reply_to[0];

if(strtolower($sender->mailbox)!='mailer-daemon' && strtolower($sender->mailbox)!='postmaster')

{

$mail_details=array(

'from'=>strtolower($sender->mailbox).'@'.$sender->host,

'fromName'=>$sender->personal,

'subject'=>$mail_header->subject,

'to'=>$mail_header->toaddress

);

}

return $mail_details;

}

但是返回结果是MIME编码字符，显然不行，于是添加了imap_mime_header_decode方法后就可以了。

function getHeaders($mid) // Get Header info

{

if(!$this->marubox)

return false;

$mail_header=imap_header($this->marubox,$mid);

$sender=$mail_header->from[0];

$sender_replyto=$mail_header->reply_to[0];

if(strtolower($sender->mailbox)!='mailer-daemon' && strtolower($sender->mailbox)!='postmaster')

{

$mail_details=array(

'from'=>strtolower($sender->mailbox).'@'.$sender->host,

'fromName'=>imap_mime_header_decode($sender->personal)[0]->text,

'subject'=>imap_mime_header_decode($mail_header->subject)[0]->text,

'to'=>imap_mime_header_decode($mail_header->toaddress)[0]->text

);

}

return $mail_details;

}

最后关于邮件中文内容乱码的问题，老外肯定不会去考虑啦，其实也是比较简单，添加iconv进行字符编码格式转换即可：

function get_part($stream, $msg_number, $mime_type, $structure = false, $part_number = false) //Get Part Of Message Internal Private Use

{

if(!$structure) {

$structure = imap_fetchstructure($stream, $msg_number);

}

if($structure) {

if($mime_type == $this->get_mime_type($structure))

{

if(!$part_number)

{

$part_number = "1";

}

$text = imap_fetchbody($stream, $msg_number, $part_number);

if($structure->encoding == 3)

{

return iconv('gb2312','utf8',imap_base64($text));

}

else if($structure->encoding == 4)

{

return iconv('gb2312','utf8',imap_qprint($text));

}

else

{

return iconv('gb2312','utf8',$text);

}

}

if($structure->type == 1) /* multipart */

{

while(list($index, $sub_structure) = each($structure->parts))

{

if($part_number)

{

$prefix = $part_number . '.';

}

$data = $this->get_part($stream, $msg_number, $mime_type, $sub_structure, $prefix . ($index + 1));

if($data)

{

return $data;

}

}

}

}

return false;

}

初学PHP，感觉很多还不懂，希望能再接再厉
