How to configure the MailInsights WebMail Usage reports in GFI Archiver ( ONLY)

Answer

The WebMail Usage report helps to identify who is exchanging the most email with webmail services. It is useful to identify potential data leakage or inappropriate use of email. The report configuration can be modified to increase or decrease the report batch size and to add web mail domains to the default list.
The MIGenBatchSize  key is used to define how the query is executed for each batch.

• When upgrading to a newer version of GFI Archiver, installation files mentioned in this procedure will be overwritten with default versions making the changes void and ineffective. It is therefore suggested to keep a record of this procedure and follow it once again directly after upgrading to keep this functionality intact.
• This procedure requires to edit files manually. If edited incorrectly it can leave the server in a non-operational state. Please keep backups of any file which is edited throughout this article before saving any changes to them.

To change the report batch size:

1. Open the folder:
   • GFI MailArchiver 2014 or newer: ..\InstallationFolder\Core\Data
   • GFI MailArchiver 2013 or older: ..\InstallationFolder\Core2\Data
2. Open product.config using notepad
3. Enter the following text to change the size of each batch:
   • <add key="MIGenBatchSize" value="500" /> 
4. Save the file

NOTE: A very low batch size can decrease performance. Setting the batch size too high increases the risk that the “search query too long” error is returned. The default value is 300.
The MIWebMailDomains key defines the web mail domains the report takes into account. To add webmail domains to the report configuration:

1. Open the folder:
   • GFI MailArchiver 2014 or newer: ..\InstallationFolder\Core\Data
   • GFI MailArchiver 2013 or older: ..\InstallationFolder\Core2\Data
2. Open product.config using notepad.
3. Enter the following text to change the size of each batch:
   • <add key=”MIWebMailDomains” value=”hotmail.;gmail.;googlemail.;yahoo.;live.;aol.;facebook.;yandex.ru;seznam.cz;gawab.com;gmx.com;mail.ru;hushmail.com;rediff.com” />
4. Save the file

NOTE: The above is the default list and additional domains have to be added to this list. For variations of top level domains, for example hotmail.co.uk and hotmail.com, enter just the first part followed by a period ‘.’ Example: ‘hotmail.’
