Greylisting is a front-line defense in which every inbound email originating from external sources is initially rejected and returned to the source server with a request to send the email again.

Spam servers tend not to be SMTP-compliant and it is unlikely the email will be returned. In the event a spam email is returned, it is highly likely to be identified and blocked by a second-line test.

The option exists to whitelist trusted senders in order to bypass the greylisting process, but it is recommended this option is used with care.

However, the following antispam agents are available only on Edge Transport servers:. Connection Filtering agent : Connection filtering uses an IP block list, IP allow list, IP block list providers, and IP allow list providers to determine whether a connection should be blocked or allowed. For more information, see Connection filtering on Edge Transport servers. Recipient Filter agent : Recipient filtering uses a recipient block list to identify messages that aren't allowed to enter the organization.

The recipient filter also uses the local recipient directory to reject messages sent to invalid recipients. For more information, see Recipient filtering on Edge Transport servers. Although the Recipient Filter agent is available on Mailbox servers, you shouldn't configure it. When recipient filtering on a Mailbox server detects one invalid or blocked recipient in a message that contains other valid recipients, the message is rejected.
