## Properties

| Property | Value |
|---|---|
| Access | Internal |
| Permissions | tabledata "Email Rate Limit" = rimd, tabledata "Email Account" = r, tabledata "Email Outbox" = r, tabledata "Sent Email" = r |

## Procedures

- `RegisterRateLimit(var EmailRateLimit: Record "Email Rate Limit"; RegisteredAccount: Record "Email Account"; RateLimit: Integer)`
- `UpdateRateLimit(RegisteredAccount: Record "Email Account")`
- `IsRateLimitExceeded(AccountId: Guid; Connector: Enum "Email Connector"; EmailAddress: Text[250]; var RateLimitDuration: Duration): Boolean`
- `IsConcurrencyLimitExceeded(AccountId: Guid; Connector: Enum "Email Connector"; EmailAddress: Text[250]): Boolean`
- `GetEmailOutboxCurrentProcessingCountDuringPastOneHour(AccountId: Guid): Integer` (internal): Returns the current count of emails in the outbox that are being processed for current user within the past 1 hour.
- `GetRateLimit(AccountId: Guid; Connector: Enum "Email Connector"; EmailAddress: Text[250]): Integer`
- `GetConcurrencyLimit(AccountId: Guid; Connector: Enum "Email Connector"; EmailAddress: Text[250]): Integer`
- `GetMaxRetryLimit(AccountId: Guid; Connector: Enum "Email Connector"; EmailAddress: Text[250]): Integer`
- `GetDefaultConcurrencyLimit(): Integer` (internal)

Plus 3 local procedures.

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 8900 "Email Impl"](../codeunit/8900.md) (1 call: `IsRateLimitExceeded → GetEmailOutboxSentEmailWithinRateLimit`)

## Called by

- [Page 8887 "Email Accounts"](../page/8887.md) (3 calls: `OnAfterGetRecord → GetConcurrencyLimit`, `OnAfterGetRecord → GetMaxRetryLimit`, `OnAfterGetRecord → GetRateLimit`)
- [Codeunit 8888 "Email Dispatcher"](../codeunit/8888.md) (2 calls: `OnRun → IsConcurrencyLimitExceeded`, `OnRun → IsRateLimitExceeded`)
- [Codeunit 1597 "Email Upgrade"](../codeunit/1597.md) (1 call: `SetDefaultEmailMaxConcurrencyLimit → GetDefaultConcurrencyLimit`)
- [Codeunit 8887 "Email Test Mail"](../codeunit/8887.md) (1 call: `OnRun → IsRateLimitExceeded`)

## Across versions

- Changed (declaration) in: BC26

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "Email Rate Limit Impl.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
