Trend Micro ScanMail Exchange Suite Vs Brightmail Antispam

hi,
can any body shed some lights or compare for us between Symantec brightmail antispam and Trend Micro ScanMail Exchange Suite .
currently I have brightmail 6.2 sitting on a dedicated WIN2K3 server (smtp gateway) and I have Scna Mail for Exchange (version 7) installed on my Exchange 2003 server,
scan mail was previously focused on virus detection but now they do include antspam.
my question is can I safely ditch the brightmail and depend only on scanmail (to reduce over head and hardware resources) ?
thx

I would suggest not. I have scanmail installed as you do, but also have Tremd IMSS on my Gateway for spam. Once you move brightmail off your Gateway, the spam is going to hit your Exchange Server directly. And depending on how much you get -- could cause your Exchange Server to drop-off considerably in performance.

thank you for your very good point. the reason I thought of this, is that we are developing  DR setup AND i WOULD LIKE TO put an exchange server on an offsite location for failover, and I didn't want to have to do 2 servers (with bright mail).
any suggestions ?

Well, I would say that depends on "exactly" what you intend to do. For instance, if your additional Exchange Server is going to use the same entry and exit point to the Internet (Brightmail Server in your case, as the "Smart Host") then there would be no need of having an additional server (Brightmail) set up. Traffic would be routed to and from the outside via the existing Brightmail Server -- and scanmail on your new Exchange Server as an added measure would suffice.

this subject is taking a turn, but that works  in my favour.
my plan is to replicate my network (critical servers) in an off site location and be able to fail over in case of any problem in any server. and since this cost money  i was wondering how will this work if i don't replicate the brightmail server ???

Yes, the subject has taken a turn. I've provided you with the information to the original question. Planning a network replication strategy is something quite different from the subject of this topic.
