Recipient Filtering - Exchange 2013 RRS feed

  • Question

  • Is Exchange 2013 Recipient Filtering  is broken ?

    I have just come across an issue that when enabled, with the following config:

    Name                       : RecipientFilterConfig

    BlockedRecipients          : {}

    RecipientValidationEnabled : True

    BlockListEnabled           : False

    Enabled                    : True

    ExternalMailEnabled        : True

    InternalMailEnabled        : False

    If someone sends a message to a bunch of your users and one of them is invalid – none of the other recipients receive the message; it would be bounced. To make it more annoying Exchange receives the whole message before it is bounced, so it wastes bandwidth as well.

    At the moment i have turned it off. Can some please advise me if i have missing something with the recipient filtering.

    Thanks

    Neil

  • Recipient Filtering should only be enabled on Edge Role Servers:

    Although the Recipient Filter agent is available on Mailbox servers, you shouldn't configure it. When recipient filtering on a Mailbox server detects one invalid or blocked recipient in a message that contains other valid recipients, the message is rejected
