Hi @Marsooq-Akkaradathil ,


If the email address is visible in the traffic's payload then you should be able to create a custom signature that matches the email address and block the traffic ... you'll might have to decrypt traffic though.


That said, could you please elaborate on what exactly you're trying to achieve ? Block 1 specific address/domain/email service ?
