One of the more ubiquitous MTAs out there has a feature called
"connection caching" where it will keep some fixed number of outbound
SMTP connections around, cycled using an LRU method, in case a new
message arrives that is routed to a recent destination to avoid the cost
of making a new connection and doing the initial SMTP negotiation.

I believe Postfix and Exchange can do this.

Our server also does something along these lines. (It's a little more complex
because it ties in to how many simultaneous threads you allow to connect to a
given destination.)
