Hybrid Exchange: anti-spam transport rules for EOP headers on on-premise Exchange 2010 not applying.


  • Hi

    I created the 3 transport rules on the on-premise Exchange mentioned in this article:

    These rules are not applying, in a test message I verified that the mentioned header
    X-Forefront-Antispam-Report is populated:


    The header contains "SFV:SPM" so the first rule should be applying... I checked the message tracking log for the test message but it just delivers...

    I enabled pipeline tracing on the on-premise transport hubs but no rule tracking files are created (even though a different rule was applied).

    Any ideas?

  • Hi.

    Please check your rule and enable for every rule - Stop processing more rules.

    Mail flow rule actions in Exchange Online Protection

    Properties of this rule section > Stop processing more rules

    More options > Properties of this rule section > Stop processing more rules



    Specifies that after the message is affected by the rule, the message is exempt from processing by other rules.

  • Hi Oleg

    Note that even though I posted it in the Exchange Online forum (due to it being an hybrid environment), the transport rules are located on the on-premise Exchange where I don't have that option.

  • Hi Glenn.

    1. This is rule available in EOP and you must be added Stop processing more rules in EOP.

    2. Check again this instruction, because it's works.

    Ensure that spam is routed to each user's Junk Email folder

     And last. 

    Public full email with all metadate or you can analyze on this site.

    Other way open case in EOP MS support, if you can't public full body email. 

    MS Support can generate test email for your domain and your rule.

    You don't need pay for case in EOP support.
