Message tracking

This area displays detailed information about the processing of emails. You can see which emails were blocked or let through, as well as trace the procedure of NoSpamProxy®and the functioning of the rules.

TIP: The NoSpamProxy Web App offers additional search options for message tracking. See Message tracking (Web App).

Enabling message tracking

1. Go to Configuration > Advanced settings > Monitoring.
2. Click Modify.
   
3. On the Message tracking tab, select the Gather message tracks option.
4. Configure the following options:
   • Store summaries The period of time for which you can trace emails. The message summary information only allows you to see in the message tracking overview whether and when the email you are looking for has arrived and whether it has been accepted or rejected.
   • Store details The retention time for the associated message details. In the details you will find the ratings of each filter, information about the origin of the email and the duration of the analysis, as well as other useful information. Since this information makes up the majority of message tracking, it is possible to keep it for a shorter period of time than the summary information.
   • URL Safeguard The period of time for which the visits of the targets of URLs are stored.
   • Store statistics The period for which you can create reports. To be able to create a meaningful report, we recommend a minimum retention period of 12 months. 
5. On the Emails on hold tab, configure the retention period for emails that are waiting for an encryption key.
   
6. Click Save and close.

Filtering search results

You can use the following search criteria individually or in combination to filter the results.

Dispatch period By selecting under Periods, frequently required searches can be selected quickly.

NOTE: A time period must be specified in any case. By default, the start time is set to the current system time - 1 hour and the end time is set to the current day at 23:59.

• Sender and recipient address The email addresses of the communication partners. It can be filtered for local and external addresses. The search can be performed for exact hits or for components of addresses. The search for exact hits is much faster.
• Subject The content of the subject line.
• Message ID The internal identifier of the email.
• Delivery results The status of the delivery.
• SCL value The calculated spam confidence level.
• Rule The name of the rule by which the message was processed.

TIP: When entering text, you can always enter the entire text to be searched for or just parts of it.

The search results are sorted by date in ascending order.

Notes

NOTE: Please consider the data protection regulations existing in your company when configuring this section.

NOTE: In order not to let the database size of the message tracking and reports grow uncontrolled, the Intranet Role cleans up the database on a regular basis. All elements that have exceeded a specified age are deleted from the database.

NOTE: If you want to discard all message tracking records and statistical data, please select the option Disable message tracking completely under the Advanced Settings of the Gateway Role. In this case no data will be collected. For example, if you only want to record statistical data, select the option Message tracking records are deleted immediately to delete all message tracking records at 2 a.m.

NOTE: If you receive several tens of thousands of emails or spam emails per day, the database size limit may be exceeded with an Express Edition SQL Server. With so many emails, shorter retention periods of message tracking records should be chosen or a SQL Server database should be installed without this limitation.
