Frequently Asked Questions

1. Can I block emails from a specific subject line?

Yes. In the filter condition, you need to select ‘Subject’ instead of ‘From’, and enter the keywords to match.

2. Will the filter work if I’m not logged into RoundCube?

Yes. The filter works server-side, so it blocks emails regardless of whether RoundCube is open or not.

3. Can I block emails from multiple senders in one filter?

You can’t directly add multiple ‘From’ conditions in one filter in some versions of RoundCube. Instead, create individual filters for each sender or use wildcard domains to block groups.

4. Do filters work instantly?

Yes, filters take effect immediately on new incoming emails after being saved. They won’t remove emails already in your inbox.
