Email security recommendations
We are looking at replacing our current email setup. At the moment, we have a pair of Clearswift email gateways, with a mimesweeper spam scanning server behind it.
The Email gateways work as a first point to remove obvious spam based on content filtering, virus scanning and ldap queries. Mail then passes on to the mimesweeper for an added layer of spam filtering.
We would like to consolidate these two parts into one. I can see Barracuda and Ironport are the main providers of appliances, but we are open to software based solutions too.
Most important requirements:
-High availability
-Redundancy
-Reliability
-LDAP query
-AV scanning
-Filtering based on header
-Reasonable cost
-Suitability for 250 users, peak of 700 mails per minute
Looking for recommendations from those that have experience with any solution that may fit.

Another point is we have 2 sites. One main site, which holds the current mimesweeper, gateway setup and Exchange server. But we also have a data centre location for high availability databases and web servers.
It would be possible for us to setup an appliance here too, and possibly another exchange server.
Would it be worth having an appliance from one vendor at the main site, and another at the data center from a different vendor? This would eliminate downtime in the case of a vendor-specific issue/outage.
Any thoughts on possible use of the second location?

I thought that was already your plan. Right now sounds like you have one Exchange server. If you run 2 the second would need to be mirroring the DBs with the filter in standby until a failure caused mail flow to jump to the second sight.
Are you wondering how to get 2 mail servers with duplicated data?
About how to get mail traffic to failover to another destination path?

That's right, one exchange server currently. I'm not looking for howto, just recommendations on appliances, and configuration.
Eg. comparions between ironport, messagelabs, Barracuda, exchange setup in both sites.

We have very tight SLAs regarding the turn around time of e-mails, the contents of mails must be processed and published within ten minutes - so I don't think that a hosted or cloud based platform would be suitable.
We need to be fully in control of our mail - this is the reason for the multiple Mail gateways (over multiple MXs from Multiple ISPs)
Main concern here is that an issue with Clearswifts licencing service knocked out both nodes last week - so we sould like to diversify at least one of our mail paths by using another vendor.
