  • Smtp error 5.1.7 missing mail attribute

    A handful of existing users within our Exchange 2003 org. have lost their "mail" attribute value. They could not receive mail until I used ADSIEdit to restore their SMTP address value to their "mail" attribute. THe thing is these are long time existing users and I can find no explaination for why the attribute changed. Our Exchange servers are enterprise 2003 SP1. Does anyone know of a bug, or recent Windows update, or a problem within Exchange that could effect some users in this way? The NDR is posted below

    The e-mail address could not be found. Perhaps the recipient moved to a different e-mail organization, or there was a mistake in the address. Check the address and try again.
    <mailserver.mydomain.com#5.1.7>

    There is no update that I know of that would remove that attribute. Windows Updates do not remove configuration information, they don't touch that area.

    The NDR you have received is what I would expect you to get if the SMTP address has been removed. Exchange doesn't recognise the user account.

    The cause of your original problem? Something has touched the domain and removed those attributes. What that was I wouldn't like to say. Could be an application, could be a person. May not have been malicious, but someone who didn't know what they were doing.
    It could also be a sign of corrupting in the domain, poor replication, something like that.

    Any reason you are on SP1? It isn't clear whether that is Windows or Exchange, but both should really be on SP2. Both service packs are rock solid, and there is almost no reason why you shouldn't deploy them.

      Thanks Sembee. We have pretty good control over account management however I will check the audit logs to see if someone has made changes out of turn. As for SP1 I mean both Windows and Exchange are SP1. Hopefully deploying SP2 Windows and Exchange this spring (long todo list, not enough hours). I am concerned with corruption and/or replication issues, except I think this occurance seems very specific and I don't see other "random" events or hints that would indicate a larger AD/replcation issue.

      Also, the "Automatically update email adddresse based on recipient policy" check box in ADUC, on the Email address tab, is not checked. Could the "mail" value go away or timeout? Could Recipient Update Service have an affect? Understand, that we have not changed our primary smtp address or default recipient policy since install 4 years ago.

        I hope you aren't as slack with Windows Updates that are released by Microsoft each month. Exchange 2003 SP2 has been out for over two years. It made changes to the way that ESM works that I cannot even remember how to do certain things (like public folder replication changes) in pre SP2 without sitting still and scratching my head.

        Sorry, but people are that behind on updates annoy me, it also makes the task of fixing problems harder because you could be looking at an issue that is resolved by one or other of those updates.
        In the current network security environment, the "ain't broke don't fix it" excuse (which is the one I hear most often) does not apply. Unless there is a vendor problem then the service packs should be deployed quite quickly after release - the days of NT4 SP2 are long gone.

        On the specific, there is nothing I am aware of that could remove that attribute automatically. No timeouts, no resets, nothing. Having the option to allow RUS to update the email addresses wouldn't affect the issue either, because all that would do is change the email address, not remove the attribute. RUS is also unable to remove email addresses, it will just add new ones or correct them.
        Something or someone has changed it.

        Simon.
