Global Email Filters with existing rules
When to use global vs per-mailbox
A common pattern: a global filter discards mail from a known-bad domain across the whole account, while individual mailboxes have their own filters for personal sorting.
Create a rule
1
Click Create a New Filter
Top of the page.
2
Name the filter
Helps you identify it later. Something like “Discard newsletter from old vendor”.
3
Build the condition
Pick a header (From, Subject, To, Body, etc.), a comparison (contains, matches regex, begins with), and the value to match.Add multiple conditions if needed. Combine them with And (all must match) or Or (any can match).
4
Pick the action
Common actions:
- Discard message — silently drop the mail. Sender doesn’t know.
- Redirect to email — forward to another address.
- Fail with message — bounce with a custom error.
- Deliver to folder — drop into a specific IMAP folder (e.g.
INBOX.Spam). - Pipe to a program — hand off to a script (advanced).
5
Save and test
Use the Filter Test field below the filter list to paste an example message and verify the rule matches before relying on it in production.
Tips
- Test before you trust. A wrong condition can silently discard legitimate mail. The Filter Test box on the same page lets you paste a real message and check what would happen.
- Order matters. Filters are evaluated top-down. Use the up/down arrows to reorder when one rule depends on another (e.g. a “tag as spam” rule before a “discard if tagged” rule).
- Regex carefully. Filter rules support regex on headers and body. Powerful, but easy to over-match. Prefer “contains” or “begins with” when you can.
