Pitbull Mail Security
Active DSN/Bounce mode can now be saved reliably from the panel.
Highlights
Bounce/DSN notifications no longer bloat the queue; error evidence stays in logs while unnecessary mail generation can be stopped.
Highlights
Live SMTP deliveries are now tied to the provider transport policy engine. Selected transport and egress path are visible in logs.
Highlights
Duplicate queue/spool creation for the same message is prevented.
Highlights
Newly added transports now display correctly in the transport pool management panel.
Highlights
Panel and worker performance improved for large queues.
Highlights
A 50 Test button was added to Outbound Delivery > Provider Status actions. Without removing provider or transport pause records, up to 50 messages from the relevant provider queue can be tried immediately for controlled testing.
Highlights
The Security Filters page now uses top tabs. Scanning, Identity, Policy and Sender tabs make settings easier to read and manage for operations teams.
Highlights
Legacy pause records in passive mode are clearer on the Outbound Delivery screen. Operators can more easily distinguish active braking from record-only status.
Highlights
Tooltips were added for critical fields on the Outbound Delivery screen. Provider policy, transport pool, weight, warm-up and limit fields are now easier to understand.
Highlights
When general policy is passive or in monitoring mode, transport pool and standby selections no longer affect active delivery behaviour.
Highlights
Transport and IP pool management was added for outbound mail to major recipient platforms such as Microsoft, Gmail, Yahoo and iCloud. Traffic can be distributed in a controlled way using weight and warm-up logic.
Highlights
Trusted rules created for senders marked as false positives can now be viewed from the panel.
Highlights
The false positive workflow was improved. When releasing quarantined mail confirmed as safe, a controlled trusted rule can be created for similar trusted senders.
Highlights
Temporary errors from blacklist and reputation sources now use smarter retry behaviour. Retention runs in the background. Bulk release was added for quarantine.
Highlights
