## Whitelisting Blocked Attachments

You can create allowlist rules to whitelist specific attachment blocks. This allows you to override the default blocking behavior for trusted senders or specific scenarios. To learn how to create allowlist rules, see [Create an allowlist rule](/inbound/allowlist/create-allowrule).
