proofpoint spam filter testing

[#1]

Hi all,
FYI on Monday morning we'll be installing a new spam filtering server which will be in place for testing purposes between 9:00am and 5:00pm.
During this time the server which will be sitting between the existing spam servers and the outgoing MX servers will tag mail rather than block it.
This is only being installed on one of the MXs so not all mail will be affected, any that are will be delayed by a few extra seconds and the following servers should appear in the message headers:
X-Proofpoint-Virus-Version
X-Proofpoint-Virus-Name
X-Proofpoint-Spam-Details
X-Proofpoint-Spam-Reason
Any questions please give me a shout
Adam

Heads up that we'll be removing the Proofpoint appliance tomorrow at some point

FYI this afternoon we'll be installing a new spam filtering server which will be in place for testing purposes between 1:00pm & 3.00pm
During this time the server which will be sitting between the Ironport spam servers and the outgoing MX servers will tag some mail rather than block it.
This is only being installed on one of the MXs so not all mail will be affected, any that are will be delayed by a few extra seconds and an extra received line may appear in the message headers.
