Adding to our efforts to curb email abuse from our networks and regulate limits as per industry standards, we will be implementing the following policies :

* Outbound email rate-limits from hosting servers: 300 mails/domain/hour and 100 mails/email account/hour

* Bounce back rate-limit of 300 mails/recipient/hour

* From address spoof prevention 

These policies will be gradually implemented from next week onwards. 

Feel free to contact our support team for further clarifications.
