Version 6.4.0 Release Notes

Release Date: 31 July, 2017

New Feature

Delay Queue

A new feature, the Delay Queue, has been added to the PureMessage for UNIX with this release. Delay Queue is a technique to protect you against snowshoe spam attack. This gives the appliance the ability to hold suspect emails for a specified period of time. By delaying delivery, the appliance creates a timed interval during which new anti-spam definitions created by Sophos Labs can be received, after which the appliance can rescan the messages using the most up to date information possible.
