Not necessarily. These messages contain information on stock portfolios.
They're consequentially quite large. Plus, a 1k message is easily a 2k
message after headers. Plus you neglect to consider the time it takes to
establish the connection, resolve the domains, and have an ident request
sent (which most SMTP servers appear to do). The messages are about (rough
guess) 10-12k with headers. We were maximizing a T1 at about <10 messages
per second. However, the network is now on a T3. With 30x more bandwidth
we'd expect at least 10x more speed :)
