ERROR: RCPT not accepted from server

  • 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-AUTH LOGIN 250-8BITMIME 250-BINARYMIME 250 CHUNKING
    SMTP -> FROM SERVER:250 2.1.0 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…
