What is email filtering?
Alibaba Mail email filtering protects corporate data by automatically acting on emails that match your rules. For example, delete emails containing "invoicing service" in the body.
Overly broad rules or simple conditions, such as a single keyword, may cause important emails to be flagged as spam or blocked.

Operation method |
The action taken on matching emails. Bounce email: Returns matching emails to the sender. Mark as spam: Moves matching emails to the spam folder. The filtering rule takes precedence over the domain whitelist. Delete immediately: Deletes matching emails immediately without notification. Also applies to emails flagged as spam. |
-
You can create up to 200 domain-level filtering rules.
-
Rules are prioritized by creation order. Earlier rules take precedence. For example, if an email matches both a spam rule and a bounce rule, the earlier rule's action is executed.
-
Domain names support wildcard characters, such as *.top.
-
If you add multiple email addresses to the same condition, the addresses are evaluated with OR logic: the rule is triggered if any one address matches. Different condition rows are evaluated with AND logic: the rule is triggered only if all condition rows are matched. To require that all addresses match before the rule triggers, create a separate rule for each address instead of adding multiple addresses to one condition.
