Block messageCodeTwo Exchange Rules PRO is capable of blocking selected messages if they match the rule criteria. This can be used as an antispam filter. For example you can block messages coming from specific senders or those that include keywords defined in the Conditions tab and therefore must be considered as spam.
How it works
Typically once the message is sent from the client you cannot stop it from delivering (Fig.1.). In CodeTwo Exchange Rules PRO you can activate the Block message rule that will be responsible for intercepting and stopping messages that fit the defined criteria (Conditions) from delivering (Fig.2.).
