我正在尝试为我们的网站构建电子邮件解析器。我最终要做的是遍历带附件的邮件，如果邮件来自特定的电子邮件地址，则保存附件。
这只是初步测试，但是，我遇到了问题，请参阅下面的评论。
<?php
echo "Loading..."."<br />\n";
$mailuser="help@mysite.com";
echo "User=$mailuser"."<br />\n";;
$mailpass="mypassword";
echo "Pass=$mailpass"."<br />\n";
// had to use this because we have SSL on site and regular port 110 didn't work
$mailhost="{localhost:995/pop3/ssl/novalidate-cert}";
echo "Host=$mailhost"."<br />\n";
$mailbox=imap_open($mailhost,$mailuser,$mailpass) or die("<br />\nFAILLED! ".imap_last_error());
$check = imap_check($mailbox);
// last message parsed will be stored in the file msgcounter.dat
$firstmsg = file_get_contents('msgcounter.dat') + 1;
$lastmsg = $firstmsg+$check->Recent; // should be == last msg index + count of latest messages
echo 'First:'.$firstmsg.' - Last:'.$lastmsg."<br>";
$result = imap_fetch_overview($mailbox,"$firstmsg:$lastmsg");
print_r($result);
foreach ($result as $overview) {
echo "#{$overview->msgno} ({$overview->date}) - From: {$overview->from}
{$overview->subject}\n";
}
// the following approach didn't work either, Kept getting warnings about
// Bad message number
//
// Some messages in the sequence HAVE been deleted.
/*
for ($index = $firstmsg-1; $index <= ($lastmsg); $index++ ) {
if (strlen(trim(imap_fetchheader($mailbox, $index))) > 0) {
echo 'in message index loop:'.$index;
}
}
*/
imap_close($mailbox);
echo "completed.". "<br />\n";;
?>

IMAP是标准差和实施较差的污水池。如果你不介意一点亵渎（或者呃，很多），那就是一个臭名昭着的IMAP rant by a Ruby library dev有一些有趣的见解。
您应该考虑using someone else's code来做肮脏的工作。

好的，我现在正在努力工作的很大一部分。 我留下的唯一问题实际上是将邮件移动到另一个“文件夹”。 POP3邮箱不支持imap_mail_move，而且我不得不想出一种不同的做事方式。
我遇到的最后一个问题是知道FILE与我刚刚打开的消息有什么关系。我知道我可以使用std rename（）函数移动文件，但我发现我可以在courierimapuiddb文件中查找msgnum，文件名就在那里。
以下是我现在使用的代码，但移动文件除外：
<?php
function showProgressMsg($msg)
{
echo $msg."<br>";
ob_flush();
flush();
usleep(2500);
}
$mailpass="mymailpass";
$mailhost="{localhost:995/pop3/ssl/novalidate-cert}";
$mailuser="help@myserver.com";
include "libs/database/db_mysql.php";
$db = new Database;
$debug=false;
if($_GET['debug']= 'yes') {
$debug = true;
ini_set('output_buffering', 'Off');
ob_start();
}
if($debug) {showProgressMsg('Opening Mailbox');}
$mailbox=imap_open($mailhost,$mailuser,$mailpass) or die("<br />\nFAILLED! ".imap_last_error());
// The IMAP.xml file contains the email address and user_id of the users that we accept
// their files via email
if($debug) {showProgressMsg('Reading IMAP.xml');}
$xml = simplexml_load_string(file_get_contents('IMAP.xml'));
$result = $xml->xpath('item');
while(list( , $node) = each($result)) {
$email = $node->LI_email;
$user_id = $node->LI_user_id;
$search = "RECENT FROM \"$email\"";
if($debug) {showProgressMsg('Searching for '.$email);}
$result2 = imap_search($mailbox, $search);
if($result2) {
$index = $result2[0];
$structure = imap_fetchstructure($mailbox, $index);
$attachments = array();
if(isset($structure->parts) && count($structure->parts)) {
if($debug) {showProgressMsg('Handling attachments');}

'is_attachment' => false,

$attachments[$i]['attachment'] = quoted_printable_decode($attachments[$i]['attachment']);
}
}
} // for($i = 0; $i < count($structure->parts); $i++)
} // if(isset($structure->parts) && count($structure->parts))
// Now add a record into the file_upload table
for($i = 0; $i < count($attachments); $i++) {
if (strlen(trim($attachments[$i]['filename'])) > 0) {
$path_parts = pathinfo($attachments[$i]['filename']);

问题是我没有检查此行中的imap邮箱：
$mailhost="{localhost:995/pop3/ssl/novalidate-cert}";
这是正确使用的行：
$mailhost="{localhost/imap/ssl/novalidate-cert}";
