Policy Manager
Here are answers to frequently asked questions on the Policy Manager feature.
- How do I create and use email policies?
- Always create policies on gateway servers using the SMTP addresses and on mailbox servers using Active Directory (AD) groups. On Mailbox server, designing policies based on SMTP addresses will be very costly, as the product does not get SMTP addresses and in order to resolve the same, AD queries are made. Doing this will slow down the performance on the Mailbox servers.
- Do domain names in policies affect performance?
- Yes. For detailed explanation, see the previous question How do I create and use email policies.
- How does policy priority work?
- Whenever a child policy gets satisfied first based on the priority of resolution, the next policy is never evaluated.
- Is it beneficial to have multiple policies and will it affect the server performance?
- Yes, this will affect performance. During policy evaluation, when the first child policy is not satisfied and next policy is evaluated, there may be AD queries which might have to be made, thus resulting in slow performance.
- How do I configure MSME to block executable files at a granular level?
- You can do this using the File Filtering Rules option. For example, let us see how to filter specific executable files such as the Windows executables.
-
1 From the product's user interface, click .5 Specify a rule name and under File category filtering, select Enable file category filtering. 2 Under Core-Scanners, click File Filtering and enable this option. 6 From File categories list, select Other specific formats. 3 Under Options (Core Anti-Spam Settings), click Edit. 7 From Subcategories list, select Windows Executables. 4 Under Available rules drop-down list, select <Create a new rule…>. 8 Click Save. - What type of file is detected as Packers or PUPs, and from where I can control this setting?
- Packers and PUPs belong to the malicious content category that is detected based on the category. Packers generally are files that are compressed or packed using some algorithm and then get de-compressed on execution.
Control this setting from Anti-Virus settings in the MSME user interface.
