Mailprotector's CloudFilter service includes the ability to queue mail for up to 7 days, should your mail server be offline. This function is included in your basic CloudFilter service, requires no additional steps to activate, and is entirely automated.
If your mail server goes down we will continue to accept mail for your domain queuing it for up to 7 days, until your server is back online. Once your mail server is operational, we will deliver your mail in a flow controlled manner to ensure that your network isn't overwhelmed.
If you're experiencing a serious or long-term outage, we would recommend enabling our XtraMail service.
