; XAMPP IMPORTANT NOTE (1): If XAMPP is installed in a base directory with spaces (e.g. c:\program filesC:\xampp) fakemail and mailtodisk do not work correctly.
; XAMPP IMPORTANT NOTE (2): In this case please copy the sendmail or mailtodisk folder in your root folder (e.g. C:\sendmail) and use this for sendmail_path.  
; XAMPP: Comment out this if you want to work with fakemail for forwarding to your mailbox (sendmail.exe in the sendmail folder)

问题是我的防火墙阻止了sendmail.exe的发送..在防火墙中设置了例外，并且有效！

Sometimes it is also an antivirus blocking it. In my case, McAfee's access control lists were the culprit. Disable access control in your antivirus, and you're probably good to go. It was quite frustrating though, finding what was causing the error.
