Mimecast provides reports to assist Administrators to manage their internal environment, through data load analysis and user efficiency. See the Reporting page for full details.
Some of this data, together with other logs, are made available in a daily file. Administrators can download the report data in a comma separated (.CSV) format. This has many uses, including sharing it with colleagues who do not have access to the Mimecast Administration Console. For data that is not retained on Mimecast eternally (e.g. Rejection Viewer logs) Administrators can access this data, even after it is no longer visible in the Administration Console.
Accessing the CSV Data
To access the daily CSV data that has been exported for your account:
- Log on to the Administration Console.
- Click on the Administration toolbar button. A menu drop down is displayed.
- Click on the Reporting | CSV Data.
Information regarding the report start/end dates, generation date, and report interval is displayed. By default a month's worth of reports is available for download, however, you can click on the calendar control to amend this
- Click the Download CSV button in the Action column to open or save the report.
- Click the Download PDF button in the Action column.
- Specify a Location for the download.The default file name is based on your Mimecast account number. This can be changed as required.
- Click the Save button. The CSV file is downloaded to your specified location.
CSV Data Report Types
To change the display filter, click on the View CSV Data toolbar button, and select one of the options:
|Rejections||Details regarding the rejected traffic is displayed. This includes the date and time, sender and recipient address, remote IP address, remote mail server name and greeting, and the rejection reason and description.|
Queue Retention Periods
Mimecast tables, queues, and viewers display information on email data for a specific length of time. A summary of these is displayed below:
Based on the retention period of your account. This includes all held, stripped, or stripped and linked attachments.
14 days by default. If you need to adjust this time period, contact your account manager who can look into your request on a case by case basis.
When messages expire from the held queue, they're still available in the archive for your account's retention period.
|Delivery Queue||Delivery retries for six attempts (or one hour) after which a warning message is sent. After 30 attempts (four days) delivery fail or soft bounces.|
|Gateway||Accepted Email||Two to six hours, at which point a successfully delivered email is archived. Alternatively, emails remain in Accepted Email until they reach their final state (e.g. delivered successfully or failed in delivery).|
|Tracking||Administrators can only search the last 30 days worth of data.|
|Reputation Based Checks||Auto Allow||Eternal|
|Greylisting (Passed)||30 Days|
This is based on your Mimecast subscription. Content Preservation (Days / Minutes) and Metadata Preservation (Days / Minutes) policies can decrease the retention period for specific users, groups, or domains.
User retention and retention adjustments allow you to purge emails based on their lifespan, while litigation holds can be used to override all purge policies.
