Q: How do I add an email address to my "bad senders" or "good senders" list with Spam Quarantine? What options are available (e.g., wildcards)?


You will need to log into your Brightmail Spam Message Quarantine, which includes links to manage your "bad senders" and "good senders" list.

Once you have navigated to the list you may follow the instructions below:

Add Bad Senders or Add Good Senders: Enter email addresses or domain names to add to your bad senders or good senders lists, separating multiple entries with commas.

Delete: Delete the selected email addresses or domain names from your bad senders or good senders lists.

Enable: Enable the selected email addresses or domain names in your bad senders or good senders lists.

Disable: Disable the selected email addresses or domain names in your bad senders or good senders lists.

The most effective way to filter bad senders is to add the address that is in the Return-Path header, this might not match the From header. See this KB page on how to view full email headers

Specifying a domain matches all senders from that domain. For example, if you specify the domain, the following senders would match:,, and

You can use the * and ? characters to match multiple senders. Use ? to represent any one character. For example, kar? will match and Use * to represent zero or more characters. For example, sam* will match,, and

Email addresses and domain names are not case sensitive, meaning that it doesn't matter if you type a blocked or allowed sender using upper case, lower case, or a mix of both.

Please note: you are limited to a total of 200 entries in your combined Good Senders and Bad Senders lists.
