Manage Whitelists and Blacklists

Notice that the best way to add whitelist records is using the Spam Monitor reports, as it automatically delivers the email and adds the sender to your whitelist. Our system uses the Sender instead of the From in the email header for blacklist and whitelist, which is automatically done if you authorize emails through spam reports.

If you enter an email address manually to your black or whitelist and notice it doesn't work, check the email header and look for the X-Barracuda-Envelope-From: field, which should be used. Yet another possibility is that the sender might change every time you receive a certain email. In this case, you can use Rules to delete undesired messages based on the part of the From header address or subject.

Besides being able to whitelist or blacklist an address for the entire domain manually, Administrators can also manage the automatic whitelist. The automatic whitelist is a domain-wide whitelist built from the email-sending patterns of all your users. It ensures that communication with trusted recipients always goes through without being filtered.

Add a sender to the whitelist.

This will treat the sender as safe and deliver all incoming emails to the Inbox folder (or another folder if you have set up delivery rules)

Add a sender to the blacklist

This will treat the sender as high-risk, and all incoming emails from this sender will be rejected (no copy of the email will be saved).

Remove a sender from the whitelist or blacklist

Sometimes, users accidentally whitelist or blacklist a sender, and you might wish to remove those entries.

Limiting by IP: add the sender's IP to whitelist or blacklist

Sometimes, you need to blacklist or whitelist an entire IP.
