- * PHP Sendmail for Windows.
- *
- * This file is rewriten specificly for PHPFI. Some functionality
- * has been removed (MIME and file attachments). This code was
- * modified from code based on code writen by Jarle Aase.
- *
- * This class is based on the original code by Jarle Aase, see bellow:
- * wSendmail.cpp It has been striped of some functionality to match
- * the requirements of phpfi.
- *
- * Very simple SMTP Send-mail program for sending command-line level
- * emails and CGI-BIN form response for the Windows platform.
- *
- * The complete wSendmail package with source code can be located
- * from http://www.jgaa.com
