How to Create a Spam Filter in Centennial Arts Webmail
If you’re receiving unwanted emails and want to automatically move them to Trash, you can create a custom filter through your Centennial Arts Webmail account.
Follow the steps below to create your own SPAM filter:

Go to https://webmail.centennialarts.com and log in with your email credentials.
Navigate to Filters
- In the top right corner, click Settings.
- In the first column, click on Filters.
- In the second column under Filter Sets, make sure Default is enabled (should be highlighted in bold).
- If it’s grayed out, click the gear icon at the bottom of the column and choose Enable.
Create Your Spam Filter
- In the third column under Filters, click the + (plus) icon near the bottom to create a new filter.
- Fill out the form as follows:
Filter Setup:
- Filter Name:

Select the option:matching any of the following rules

or justdomain.com
- Example:
- Click the + icon to the right to add another rule for a different email or domain.
Actions:
- Under …execute the following actions, select:

→Trash
- Make sure to add one final action:

What does “Stop evaluating rules” mean?
This ensures that once a message matches one of the conditions and is moved to Trash, no further filters will be processed on that message. This helps prevent conflicts or unnecessary actions being applied to spam.
Save Your Filter
Click the Save button at the bottom of the filter panel.
Important Note:
Each filter can include up to 38 rules/actions. If you need to block more than 38 emails or domains:
- Create a second filter.
- Name it:
Move to Trash 02
- Follow the same setup process.
