Setting Up Email Whitelists and Blacklists in Virtualmin

Why are Whitelists and Blacklists Important?

As a small organization, you want to ensure that important emails from customers or partners do not end up in the spam folder. At the same time, you want to block annoying spam messages. With whitelists and blacklists in Virtualmin, you have control over your email traffic.

What are Whitelists and Blacklists?

A whitelist is a list of senders from whom you always want to receive emails – these will never be marked as spam. A blacklist contains senders whose messages you want to block entirely.

Step-by-Step Guide for Virtualmin

1. Accessing Email Settings

Log into Virtualmin and select the desired server or domain. Then go to Email → Spam Protection.

2. Configuring Whitelist

Click on Whitelist and add the desired email addresses or domains. You can also use regular expressions to define patterns. Save the changes.

3. Configuring Blacklist

Switch to the Blacklist tab and enter the senders you want to block. Regular expressions are also possible here. Save the list.

4. Setting Priority and Exceptions

Note that whitelist entries take precedence over blacklist entries. If an address appears on both lists, the email will be delivered. You can also set up global whitelists for all domains.

Tips for Small Organizations

• Regular Maintenance: Check your lists regularly and adjust them to new requirements.
• Documentation: Record why you whitelist or blacklist certain senders – this helps with team collaboration.
• Testing: Send test emails from whitelisted and blacklisted addresses to ensure the filters are working correctly.

Additional Protective Measures

In addition to whitelists and blacklists, Virtualmin offers other anti-spam features such as SpamAssassin. Combine these tools for optimal protection. For your email infrastructure, you can rely on professional web hosting that integrates such features.
