Create email allow policy

POST/accounts/{account_id}/email-security/settings/allow_policies

Creates a new allow policy that exempts matching emails from security detections. Use with caution as this bypasses email security scanning. Policies can match on sender patterns and apply to specific detections or all detections.

Security

API Token

Example:Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY

API Email + API Key

The previous authorization scheme for interacting with the Cloudflare API, used in conjunction with a Global API key.

Example:X-Auth-Email: user@example.com

The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys.

Example:X-Auth-Key: 144c9defac04969c7bfad8efaa8ea194

Path ParametersExpand Collapse

account_id: string

Identifier.

maxLength32

Body ParametersJSONExpand Collapse

is_acceptable_sender: boolean

Exempts messages from this sender from Spam, Spoof and Bulk dispositions only; Malicious and Suspicious dispositions still apply.

is_exempt_recipient: boolean

Bypasses all detections for messages to this recipient.

is_regex: boolean

is_trusted_sender: boolean

Bypasses all detections and link following for messages from this sender.

pattern: string

The pattern value to match. The format depends on pattern_type: a valid email address for EMAIL (e.g. user@example.com), a valid domain name for DOMAIN (e.g. example.com), or a plain IPv4 address or IPv4 CIDR block for IP (e.g. 1.2.3.4 or 1.2.3.0/24); the API accepts only globally reachable IP addresses and rejects private, loopback, link-local, and unspecified addresses.

maxLength1024

minLength1

pattern_type: "EMAIL" or "DOMAIN" or "IP" or "UNKNOWN"

Type of pattern matching.

EMAIL: matches a full email address (e.g. user@example.com)
DOMAIN: matches a domain name (e.g. example.com)
IP: matches a plain IPv4 address (e.g. 1.2.3.4) or an IPv4 CIDR block (e.g. 1.2.3.0/24). The API accepts only globally reachable addresses.
UNKNOWN: deprecated; you cannot use this when creating or updating policies, but it may appear on existing entries.

One of the following:

"EMAIL"

"DOMAIN"

"IP"

"UNKNOWN"

verify_sender: boolean

Enforce DMARC, SPF or DKIM authentication. When on, Email Security only honors policies that pass authentication.
