Email throttling allows system administrators to limit the number of emails transmitted from their mail server within a specific time period (generally 1 Hour). This limit may be in terms of:
- The number of emails sent from a particular domain.
- Usage of bandwidth over specific limit.
- The number of bounced messages received for any particular domain.
When the user reaches at this limit, his/her emails will be treated according to the Throttling Action specified by the administrator.
Note: This feature is limited for SmarterMail Enterprise Edition only.
