Description:
------------
Running a script which attaches a Word .rtf file to an email via MIME encoding. script works fine under 4.3.2, but causes the attachment to be corrupt under 4.3.3.  Not sure why, do not fully understand the code we copied to do this.

Yeah, it's ugly code that I've no time to clean up.  Sorry.  It does work without flaw on PHP 4.3.2 Win32, though.

Only change to the server was removal of 4.3.2, insertion of 4.3.3 and a restart of IIS (5).  No changes to the script were made nor to any other software on the system.



Reproduce code:
---------------
http://www.powerpointerspage.com/php_433_mime_bug.txt

Expected result:
----------------
code SHOULD produce an email addressed to a customer which contains a text message and a MIME attachment of an RTF file.  The RTF should be immediately openable by the end user upon receipt of the email.

Actual result:
--------------
Outlook reports "The file appears to be corrupt" when doing test-sends to ourselves.  So, something during the attachment process is not working the same way as it used to - base64 encoding, chunk_split(), something along those lines.

Looking at the way in generates the mime boundary, I can tell that MD5 is working right, at least.  I do get a different, "valid" md5 string on each test-send.

The problem totally disappears upon reversion to PHP 4.3.2.  Normal email attachment resumes at that point.
