Exchange Server receives a vast number of emails in business organizations, in addition to sending many emails outside the organization. And Exchange Administrator must secure its mail recipients from external threats like spamming, phishing, virus attacks, and hacking attempts. Microsoft has some inbuilt protection like anti-malware and anti-spam feature which you can configure to safeguard the data.
NOTE: These agents are by default ‘Enabled’ on Edge Transport Servers.
Let’s dig deep and learn how we can enable the anti-spam protection using various transport agents. But first, understand how they work and protect the data.
In the typical condition, the Exchange Administrator needs to enable the anti-spam agents on Mailbox Servers when there is no Edge Transport server, or the organization does not have a robust anti-spam protection application. These agents have a priority value, and a lower value indicates a higher priority. Based on the default priority value, here is the order of agents in which they are applied to the messages of the mailbox –
You can install all these agents using an Exchange Management Shell script only and here is its whole procedure in a stepwise manner.
Step – 1. Start the Exchange Management Shell on Exchange Server and run the following script.
When the script runs successfully, it will ask you to restart the Exchange Server.
Step – 2. Restart the Microsoft Exchange Transport services with the command.
Step – 3. Now, mention the incoming SMTP servers which you want to ignore by the sender ID agent. You can specify multiple numbers of SMTP servers, but you need to specify at least one server necessarily.
To verify the presence of SMTP server in the configuration list, run the command –
Step – 4. Install all the agent with this command.
Check the status of each agent by running following commands one by one.
All these agents work on the mailbox server, and you need to install and configure them manually. But many administrators overlook the importance of anti-spam protection and face severe corruption issues in the Exchange. There is an in-built utility called ESEUTIL to repair the Exchange Server database using multiple switches, but they can further delete the corrupt data rather than recovering it.
Here comes the Kernel for Exchange Server Recovery software at your rescue. It is a specialized data recovery software which can handle any corruption from the Exchange database and bring all the data back to you. It also recovers the accidentally deleted messages and saves them at any desired destination.
