+*  +----------------------------- IMPORTANT ------------------------------+
+*  | Usage of this class compared to native php extensions such as        |
+*  | mailparse or imap, is slow and may be feature deficient. If available|
+*  | you are STRONGLY recommended to use the php extensions.              |
+*  +----------------------------------------------------------------------+
+*
+* Mime Decoding class
+*
+* This class will parse a raw mime email and return
+* the structure. Returned structure is similar to
+* that returned by imap_fetchstructure().
+*
+* USAGE: (assume $input is your raw email)
+*
+* $decode = new Mail_mimeDecode($input, "\r\n");
+* $structure = $decode->decode();
+* print_r($structure);
+*
+* Or statically:
+*
+* $params['input'] = $input;
+* $structure = Mail_mimeDecode::decode($params);
+* print_r($structure);
+*
+* TODO:
+*  o Implement multipart/appledouble
+*  o UTF8: ???
+
+		> 4. We have also found a solution for decoding the UTF-8 
+		> headers. Therefore I made the following function:
+		> 
+		> function decode_utf8($txt) {
+		> $trans=array("�&#8216;"=>"õ","ű"=>"û","Ő"=>"�&#8226;","Ű"
+		=>"�&#8250;");
+		> $txt=strtr($txt,$trans);
+		> return(utf8_decode($txt));
+		> }
+		> 
+		> And I have inserted the following line to the class:
+		> 
+		> if (strtolower($charset)=="utf-8") $text=decode_utf8($text);
+		> 
+		> ... before the following one in the "_decodeHeader" function:
+		> 
+		> $input = str_replace($encoded, $text, $input);
+		> 
+		> This way from now on it can easily decode the UTF-8 headers too.

+/**
+*
+*  Raw mime encoding class
+*
+* What is it?
+*   This class enables you to manipulate and build
+*   a mime email from the ground up.
+*
+* Why use this instead of mime.php?
+*   mime.php is a userfriendly api to this class for
+*   people who aren't interested in the internals of
+*   mime mail. This class however allows full control
+*   over the email.
+*
+* Eg.
+*
+* // Since multipart/mixed has no real body, (the body is
+* // the subpart), we set the body argument to blank.
+*
+* $params['content_type'] = 'multipart/mixed';
+* $email = new Mail_mimePart('', $params);
+*
+* // Here we add a text part to the multipart we have
+* // already. Assume $body contains plain text.
+*
+* $params['content_type'] = 'text/plain';
+* $params['encoding']     = '7bit';
+* $text = $email->addSubPart($body, $params);
+*
+* // Now add an attachment. Assume $attach is
+* the contents of the attachment
+*
+* $params['content_type'] = 'application/zip';
+* $params['encoding']     = 'base64';
+* $params['disposition']  = 'attachment';
+* $params['dfilename']    = 'example.zip';
+* $attach =& $email->addSubPart($body, $params);
+*
+* // Now build the email. Note that the encode
+* // function returns an associative array containing two
+* // elements, body and headers. You will need to add extra
+* // headers, (eg. Mime-Version) before sending.
+*
+* $email = $message->encode();
+* $email['headers'][] = 'Mime-Version: 1.0';
+*
+*
+* Further examples are available at http://www.phpguru.org

+ * destructor, use error_log(), syslog() or something similar.

+/**
+*  Takes HTML and converts it to formatted, plain text.
+*
+*  Thanks to Alexander Krug (http://www.krugar.de/) to pointing out and
+*  correcting an error in the regexp search array. Fixed 7/30/03.
+*
+*  Updated set_html() function's file reading mechanism, 9/25/03.
+*
+*  Thanks to Joss Sanglier (http://www.dancingbear.co.uk/) for adding
+*  several more HTML entity codes to the $search and $replace arrays.
+*  Updated 11/7/03.
+*
+*  Thanks to Darius Kasperavicius (http://www.dar.dar.lt/) for
+*  suggesting the addition of $allowed_tags and its supporting function
+*  (which I slightly modified). Updated 3/12/04.
+*
+*  Thanks to Justin Dearing for pointing out that a replacement for the
+*  <TH> tag was missing, and suggesting an appropriate fix.
+*  Updated 8/25/04.
+*
+*  Thanks to Mathieu Collas (http://www.myefarm.com/) for finding a
+*  display/formatting bug in the _build_link_list() function: email
+*  readers would show the left bracket and number ("[1") as part of the
+*  rendered email address.
+*  Updated 12/16/04.
+*
+*  Thanks to Wojciech Bajon (http://histeria.pl/) for submitting code
+*  to handle relative links, which I hadn't considered. I modified his
+*  code a bit to handle normal HTTP links and MAILTO links. Also for
+*  suggesting three additional HTML entity codes to search for.
+*  Updated 03/02/05.
+*
+*  Thanks to Jacob Chandler for pointing out another link condition
+*  for the _build_link_list() function: "https".
+*  Updated 04/06/05.

+		Pass root node to the iml_GetPart*() functions to retreive individual bits of info.

+
+	AUTHOR: Ryo Chijiiwa <ryo@ilohamail.org>
+	FILE:  include/smtp.php
+	PURPOSE:
+		Provide SMTP functionality using pure PHP.
+	PRE-CONDITIONS:
+		The functions here require a SMTP server configured to allow relaying.
+	POST-CONDITIONS:
+		The following global variables are returned:
+		$smtp_errornum - error number, 0 if successful
+		$smtp_error - error message(s)
+		$SMTP_TYPE - Optional
+	COMMENTS:
+		The optional $smtp_message_file can be used for sending extremely large
+		messages.  Storing large messages in a variable will consume whatever
+		amount of memory required, which may be more than is available if dealing
+		with messages with large attachments.  By storing them in a file, it becomes
+		possible to read/send bits at a time, drastically reducing memory useage.
+		
+		This library only provides bare-bones SMTP functionality.  It is up to the
+		parent code to form valid RFC822 (MIME) messages.
