How to white list in Zimbra webmail

Imagine waiting for that crucial email from a job application, an important update from a loved one, or an exclusive offer from your favorite brand, only to find out later that it got lost in your spam folder. Missing these emails can lead to missed opportunities, misunderstandings, and frustration. This situation is why whitelisting trusted email addresses or domains in your Zimbra Web Client is essential. Whitelisting ensures that emails from sources you trust bypass the spam filter and land directly in your inbox, so you never miss out on important information or special moments. Let’s make sure that the emails that matter to you most always find their way to you.


If you don’t whitelist an email address or domain, emails from these sources may be incorrectly marked as spam. This means they are automatically moved to your spam folder, bypassing your inbox entirely. As a result, you could miss important updates, opportunities, or communications. Whitelisting (also known as “safe listing” or “allowed list”) is a proactive measure to prevent this from happening, telling your email client that messages from certain sources are safe and should be allowed into your inbox.
