Due to our email filter being useless since the company upgraded it I am trying to use the Exchange to block TLD

I have added a Sender Filter but it still allowed the emails to come through

SerializationData : {0, 1, 0, 0, 0, 255, 255, 255, 255, 1, 0, 0, 0, 0, 0, 0...}

    Hi @JoedyF222

    I tested in my lab and it seems to work for me.

    Have you restarted Microsoft Exchange Transport service after you modified the sender filter?

    If it still doesn't work for you, you may also consider using mail flow rule instead.
    The rule would be like:
