  • Exchange Server 2003 not Receiving External Emails

    All,

    I have an Exchange 2003 Server and this morning it stopped receiving external emails. It can send no problem and can also send and receive internally.

    No changes have been made

    The emails go through messagelabs but I have bypassed this and had them sent 'directly' to our mails erver and the issue still occurs

    I have 200 users screaming at me so any help would be great



    This is the message people receive

    I was not able to deliver your message to the following addresses.
    <[email protected]>:
    xx.xxx.xxx.xx does not like recipient.
    Remote host said: 550 5.7.1 127.0.0.2

    Cheers

    Jim

    5.7.1 - unauthorised to relay email.
    Seems like all of a sudden your exchange server won't accept mail for your domain.


    it wouldn't have just happened suddenly though.

      I know it seems weird but it did.

      I received an email at 9pm and this morning not working!

        well, start by reviewing all your exchange settings, and ensure they match the settings in your initial design or configuration management database...

          I have gone through the list and I can see nothing that would lead to this issue. Any more ideas people???

                Finally solved the issue. We had Connection Filtering switched on and this was blocking emails from addresses that were on certain blacklists. It does appear that MessageLabs, whom we use to filter our Spam, had managed to get themselves on a Blacklist therefore all emails sent to us from them were instantly rejected. I spotted this some five hours earlier, spoke to Messagelabs who assured me this was not the issue thus wasting five more hours of my time looking in the wrong direction!
