Email Delivery / Possible transport rule RRS feed

  • Question

  • Hello Everybody,

    I have a situation that when one of my customers is trying to send an email to a particular domain but the email gets dropped.

    We have a cloud based email solution just like mimecast or messagelabs. 

    When the email is sent to the particular domain it gets blocked on the on premise part ( exchange 2010) 

    I understand that an transport rule is blocking it but: 

    -we have over 140 transport rules ( checked them one by one manually ) 

    -exported message tracking logs and inside of them i see that source : Agent eventid:fail but no information in the event data (its a silent drop so the email is getting blocked but no notification is sent to the sender ) 

    Just for your own information i cannot : 

    -add to each rule an bounceback 

    -turn of rules one by one 

    -use the filter parameter in transport server command  ( dont have this cmdlet in the powershell) 

    I'm struggling for the last couple days with this issue. 

    Any ideas ? 

    Thx :) !

  • output to a text file

    Get-TransportRule | select -ExpandProperty Description

    then search for the domain or address that is being blocked.

  • Additional information to Andy David's suggestion:

    You can use command below to export all transport rule to a .CSV file:

    Get-TransportRule | select Name,Description | Export-Csv c:/temp/rule.csv -NoTypeInformation

    Then open this .CSV file and use "Ctrl+F" to search key word like: "this particular domain or ","Delete" or "without notifying"

    If this email is dropped with transport rule, you will could find it in this way.

    In that case a transport rule isnt blocking it. What does message tracking show

  • As Andy David said, if there doesn't exist such a transport rule, this email may not be blocked by transport rule. Could you provide the detail information about message tracking log to us? (Remove sensitive information before posting it)

    Get-TransportService | Get-MessageTrackingLog -Sender xx@xx.xx -Recipients xx@xx.xx -MessageSubject "xx" | fl
