You can approve or block specific senders and recipients, based on the email address, domain, subdomain, attachment type, email size, words in the email or header, source country or destination country.
The Anti-Spam service detects spam by applying hundreds of rules to each message that passes through. It blocks obvious spam outright and diverts what is possibly spam to the Quarantine. If you discover that some quarantined messages are actually good mail that just looks like spam, add the senders of those messages to an appropriate approved-senders list. If a number of quarantined senders are from the same domain, such as the same company, add the domain to an appropriate approved senders list. Messages from those senders are then delivered to users in your organization, regardless of the spam-like content.
To avoid the risk of increasing spam traffic, approve only specific senders whose messages might look like spam, rather than approving all of your known senders. Also, avoid approving too many domains, as that can increase the risk of spoofing.
Step 1: Start creation
Step 2: Scope (applies only if you are not an end-user)
What does the rule apply to? There can be various selections:
Step 3: Select IF Conditions
Step 4: Rule Narrative
Step 5: Add another Condition (for IF)
Step 5: Select Do Condition
Step 6: Add another Condition (for DO)
Override the Previous Destination – If selected, this option will ignore the destination that another filter may have applied to this message. This override means we can stop another rule’s DO action from performing.
