Cisco ESA and TCP reset

[mprstacic]

Hello,

basically, I'm wondering can I configure ESA to act on TCP reset and place undeliverable email in queue of some kind for up to 72 hours?

In between Exchange and ESA there is a firewall which is not MTA capable, but can scan inline for advanced malware.

In a case of false positive I would like to be able to manually release quarantined email from queue.
Thanks!

Emails remain pending in the delivery queue when a soft bounce code is received for connections and are tracked for a destination domain, they automatically keep retrying delivery up to 3 days as per the configured bounce profile.

Delivery queue cannot be configured or controlled to release one email out of possibly multiple emails pending for a domain.

Manual control for releasing emails would be more of what a custom quarantine can do, however it cannot be used in relation to TCP resets.

Regards,
