  • I think you mean to say: "my exchange 2007 users don't receive email, however the read receipts sent from the server indicate a succcessful delivery".

    Even though I have deciphered your question you need to provide some background before we can help.

    That's correct. Your server has accepted the message for delivery and
    it sends a DSN to that effect. However, messages may still be
    undeliverable, in which case a NDR will be sent. If you have any
    anti-spam or anti-virus software they may quarantine or drop a message
    before it reaches the destination mailbox. In that case it's rare to
    have a NDR sent.

  • Hi GCSIT,

    Any update for your issue?
    1. telnet your published SMTP server for exchange 25 port, confirm you could use the cmdlets to send a email
    2. confirm your smtp address/ip not in the public blacklist
    3. post the exact error/ndr of the failed email
    4. does all the external email address have the issue when they send emails to your domain

    Regards!
    Gavin
