You are pretty much safe with any vendors that utilize the latest VSAPI version 2.5 for Exchange 2003. I recommend you take a look at the variety of cool gateway appliances that are coming out. Don't be afraid to go with a multi-vendor solution; for example, Sybari or Trend Micro for Information Store scanning and something like Iron Mail for the gateway.
