    Exchange down?

    Afternoon,

    Running exchange 2007 on a 2003 R2 box

    this is what is happening:

    Internal to internal email fine
    Internal to external email fine
    External to internal not delivering
    at home logged on through the OWA to internal mail fine (so line issue)

    Nothing at all has changed on the server, uninstalled the anti virus and spam filter. Rebooted. No message que appearing

    ANY IDEAS PLEASEEEEEEEEEEEEEEEEEEEEEEEE

    could be an MX record problem? have a look at mxtoolbox.com and run some tests perhaps?

    try running this - https://www.testexchangeconnectivity.com/

    does the external user get a bounce?

    on inbound smtp? If you open the exchange management console and go to toolbox and queue viewer do you see them sitting there?

    And does an external user get a bounce?

    Plenty of space on the server? Re-start SMTP service.

    If the external connector is saying SMTP is functioning then its more likely to be Microsoft Exchange Transport.

    1. Up the protocol logging on the Receive connector for the internet mail and check if it's hitting your Exch server.
    2. Send a test message and use MT to see if was accepted & routed & delivered.
    3. Maybe describe your topology for routing in more detail. Firewall/NAT/
    4. Any changes made?
    5. Post RCA results from SMTP tests (Inbound).

    Yes please post the NDR removing any confidential information. Put your IP/Domain into here Blocklist Removal Center - The Spamhaus Project and it will give you info. If you happy PM me the info and I'll dig through it.

    You still need to establish why you are blacklisted
