Setting Up ECE email: Spam filtering Allow and Deny ADDRESS

Preparation

1. Connect to ECE VPN is no longer required

2. Click HERE to access the web interface

3. Input your username and password. It is not a good idea to enable "Remember login permanently"

4. Expand the Mail tab in the left panel and select SpamAssassin Mail Filter, then Select Allowed and Denied Addresses

You will see a window with 4 tabs. The tabs allows you to add "Allowed addresses" and "Denied addresses", as well as some other options.

Please ignore the warning message that procmail configuration is not configured. We configure it in differenct way, and the filtering still works.

5. To whitelist email addresses, Select the "Allowed addresses" tab. Type the email address you wish to whitelist in the box next to "Senders to never classify as spam" and then click "Save" at the bottom of the screen.

All email addresses can contain wildcards, like *@foo.com or *.foo.com to match entire domains. If you whiltelist all users in a domain but want to make an exception, you can do it in the exception box. Emails' FROM address can be easily faked, you can also whitelist an email address which is only from its official domain. for example, xxx@example.com from domain example.com. But please pay attention, the official sending server of xxx@example.com is not necessary in domain example.com. You can use nslookup to check the MX entry of the server, if you are not sure of the real server, just don't use the last section in the window below.

6. To Blacklist email addresses or block the addresses, Select the "Denied addresses" tab. Type the email addresses you wish to block in the box next to "Senders to always classify as spam" and then click "Save" at the bottom of the screen.

All email addresses can contain wildcards, like *@foo.com or *.foo.com to match entire domains. If you blacklist/block all users in a domain but want to make an exception, you can do it in the exception box.
