I am in the process of sourcing for a carrier class email security solution that will replace our current edge spam gateways based on open source solutions. Some solutions that am currently considering are Ironport, Fortinet Fortimail, MailFoundry and Barracuda. I'd therefore wish to know, based on your experiences, what works for you satisfactorily.
Areas that are key for me are centralized management and reporting, carrier class performance, per mailbox policy and quarantine, and favourable licensing for an MSSP. I know Ironport is rated highly in this space but I find its per user licensing is not favourable for a MSSP.
On the other hand installing a FreeBSD system with QMail/Procmail and/or PostFIX for the other stuff is a no-brainer especially with a Webmin Management front end.

Alex there are many email systems out there - but make sure that whatever you buy can support NTPv4 and not SNTP or unauthenticated NTP since this is how the GW is going to be able to put time-marks on receipts which must have legal authority. So that means any appliance system provider must have at least NTPv4 tested with both Autokey and symmetric-key and the new interface specific ACL's in the 4.2.6 versions of NTP. Further the issues of the ECC/Parity memory become important here because time is moved over UDP and is subject to single-bit errors all over the place. Todd Glassey
