Looking through the content filter to verify that mail entering the company meets policy requirements, there is currently no other way to look at the attachments without having to first forward the mail to yourself. Which of course adds to our archiving scheme. In the next version, would it be possible to open the attachment directly from the mail filter :?: This would greatly save time clearing things out.
The M-series is used for the centralised version, because this causes a lot of load on the system. However that is the only real load, as quarantine messages is not so CPU intense.
On the C-series, the reporting is already there. (yes this cost some performance - for all those who remember switching to 5.0 from 4.7) Tracking will also use some cpu cycles and therefore will have some impact. We are positive that the impact will be low and that for those where this is still too much, the same options are available as for reporting (turning it off).
I hope that helps.
I don't have any % numbers for the performance and the testing isn't over yet, so it's hard for me to say.
