  • Not receiving specific emails

    Out of the blue, emails from one particular person are not being received. I seem to be getting emails from everyone else (although that is impossible to completely verify unless someone asks me if I received their mail), but not this one person.

    However, when I send him an email and he sends a reply, I DO receive the mail. it is only when he originates the email that I do not receive it, nor does he receive an error message.

    Any idea what is going on here and how to fix the problem? The sender is someone I need to communicate with daily, so this is a painful issue. (and I don't want to use one of my pop addresses).

    Thanks!

    a quote of the smtp session over telnet would be very helpful

      I used to think of myself as fairly proficient in the world of computers, but a response like yours makes me realize the opposite - I am terribly sorry, but I don't have a clue what you mean. I appreciate the response, but perhaps you could walk me through this a bit. Thanks! David

        Re: Not receiving specific emails

        if you are the one not receiving emails, this should be done on the sending site, to recreate the situation precisely:

        from the troublesome sending MTA console:
        Code:
        telnet your_mx_server.com 25
        
        helo sending_server.com
        
        (should be response here)
        
        mail from: <[email protected]_server.com>
        
        (should be response here)
        
        rcpt to: <[email protected]_server.com>
        
        (should be response here)
        
        data
        
        subject: the subject for the email
        some text here
        some more text
        
        .   <--- be sure to put this here - this ends the email text input
        
        
        quit

        and you're done. now copy the the whole process into here
        substitute the italics with the appropriate addresses of course

          The problem is that as the receiver there is close to nothing you can do.
          The sender needs to investigate what is happening with the messages. If they are being delivered to your server then you can investigate, but until the messages are received by your server they are completely out of your control.

          What usually happens in cases like this is the sender will say they can email everyone else, so it must be a problem with you, but that doesn't help show where the problem is.
          If the sender doesn't have their own server and/or sends email through an ISPs SMTP server then without an NDR there is almost nothing you can do.

          If you receive email through a third party then you could ask them to investigate but that is about it.
