How many emails can ITA Secure Messaging process simulataneously?
ITA Secure Messaging is designed to handle massive scalability requirements. Although each email that comes into the Rules Engine can take an average of 200 - 300 ms, multiple threads can process these emails simultaneously. These threads come from a pool of threads that the Rules Engine manages internally.
ITA Secure Messaging has been throughly tested for heavy load and stress. ITA Secure Messaging's Rules engine uses multi-threaded architecture that can handle thousands of messages per second. During our test we found that its not the CPU or memory, but network that becomes a bottleneck - you cannot open more 65536 TCP/IP sockets on a machine, which is a theoritical limit. The actual number is much smaller than 65536.
Does ITA Secure Messaging scan both in-bound and out-bound messages?
Yes. ITA Secure Messaging comes with two SMTP servers. Depending on your network configuration you can either use one or both. For more information on how to use it for outbound emails, refer to the How To Guide.
