Mail rejected for container policy reasons in Exchange 2k3

Posted on 2007-08-08
Last Modified: 2008-01-09

i get the following error message when any email comes from to my domain. i have a spam appliance from Espion called the Interceptor which then forwards emails to my Exchange 2k3 Enterprise server. I am not sure what the "container policy reasons" are as i do not have anything within Exchange that should be rejecting these emails.

Any help would be appreciated. Thanks.

    i even have these people emailing to my email address... i created a rule from within gmail to forward any emails that comes from this place to my work email. when those get forwarded i get the same error message back to gmail aswell. but any emails that i manually send to my work from gmail, make it thru just fine and without any type of problems.

    That isn't an Exchange message.
    Therefore you have to look at the appliance as the cause of the error message.See if has any logs that record why it has been rejected.

    my spam appliance people are saying that it is not them and that it is exchange rejecting the email:

    The e-mails from your gmail account to your account are getting past the Interceptor's filtering system. However, when the Interceptor proceeds to deliver the message to your end-point mail server, it is being rejected back to the sender and the 5.5.0 error is being provided by the MS Exchange server. The reason behind the Exchange server rejecting the message is usually due to not rebooting the mail server after installing any updates. We have encountered this issue in the past where system updates were installed on a Windows mail server, was not rebooted after the updates were installed and they encountered the same error message. Please let me know if I could be of further assistance.

    i have rebooted the exchange server 5 days ago, so i know that is not the case... any other ideas possibly?

    The point is though - it is not an Exchange message. Therefore unless you have something else on the Exchange server that could be rejecting the email, the message is not coming from the Exchange server.
    A google of the error points towards an antivirus package being the cause, but doesn't say which one or what the fix is.
