 * Hi,
 * Plugin looks great. I’ve tried a few that do a similar thing, but I prefer this
   as it’s better for debugging.
 * I’m running WordPress on a Windows 2008 server with Apache.
    wp_mail is working
   fine but I get the “The e-mail could not be sent. Possible reason: your host 
   may have disabled the mail() function.” error when following the lost password
   link in WordPress.
 * In the settings page I’ve entered the smtp server, port, no authentication. The
   test send email works perfectly. However, when trying the lost password feature
   again, I still get the “your host may have disabled the mail() function”.
 * Here is the full message with the debugging turned on:
 * SMTP -> FROM SERVER:220 SERVER.name.local Microsoft ESMTP MAIL Service ready 
   at Thu, 26 Sep 2013 11:14:46 +0100
    SMTP -> FROM SERVER: 250-SERVER.name.local
   Hello [10.30.1.150] 250-SIZE 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-

   Sender OK SMTP -> FROM SERVER:550 5.7.1 Unable to relay SMTP -> ERROR: RCPT not
   accepted from server: 550 5.7.1 Unable to relay
 * The e-mail could not be sent.
    Possible reason: your host may have disabled the
   mail() function.
 * I’ve changed the server name just in case it was sensitive information.
 * Where am I going wrong?

 * This I’ve found the problem. The ‘Lost your password?’ email address I used was
   an external one. As the server is a development server, I dont think it has outside
   access.
    Anyway, I tried with an internal address and it worked.
 * Not sure why the test worked with an external address though.

 * Hello. Sorry for the delay… WordPress remember password still working through
   his own wp_mail() function, the Knews config only change the Knews emails/newsletters.
 * Seems a security limitation of your webserver…
