Email Security & Antispam

Explore security controls:

Score incoming messages using server-level filtering and apply configurable thresholds for tagging or rejection.

Temporarily defer unknown senders to block automated bulk spam while allowing legitimate mail servers to retry.

Generate and validate domain authentication records that protect sender identity and improve deliverability.

Publish domain policies, monitor authentication alignment, and enforce secure mail transport where supported.

Review suspicious messages, release trusted mail, and manage sender decisions without exposing user inboxes.

Protect messages in transit with encrypted SMTP connections and modern transport security policies.

Monitor server IP reputation and common blocklists to identify delivery risks before they affect communication.

Use revocable application passwords and mailbox access policies instead of exposing primary credentials.

Inspect SMTP transactions, queue activity, authentication results, and delivery responses from one dashboard.
