Troubleshooting email protection

Emails are not delivered. They remain in the mail spool.


Automatically created firewall rules, such as the rules created when you add an IPsec connection or hotspot are placed at the top of the rule list. This can also happen with manually created firewall rules if you set the Rule position to Top.

If these rules match the criteria for SMTP traffic, XG Firewall won't evaluate other rules in the rule list. So, the rule that applies to SMTP traffic (typically, the automatically created MTA rule) isn't evaluated and emails remain in the mail spool.


  1. Go to Rules and policies > Firewall rules.
  2. In the firewall rule list, move the new rule lower to meet your requirements.
