Description:
------------
A new bug has been introduced with the bug fix listed at
http://bugs.php.net/bug.php?id=28976

The above fix attempts to set a reverse-path based on the From: header
if sendmail_from is undefined.

The problem with this is that the From: header is taken verbatim and
not formatted to the RFC 2822 specification.

This results in the email being rejected by the server.

Reproduce code:
---------------
Example:

$headers .= "From: \"Example User\" <email@example.com>";

PHP will then set  the RPath to "\"Example User\" <email@example.com>"
when it should be "<email@example.com>"

Expected result:
----------------
Line 440 win32/sendmail.c:

snprintf(Buffer, MAIL_BUFFER_SIZE, "MAIL FROM:<email@example.com>\r\n",
RPath);

Actual result:
--------------
Line 440 win32/sendmail.c:


snprintf(Buffer, MAIL_BUFFER_SIZE, "MAIL FROM:<Example User
<email@example.com>>\r\n", RPath);
