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.

And I was referring to Sendmail.

The more SMTP clients there are that do this, the more likely it is that a 
server demanding QUIT before scheduling a delivery attempt will lose mail.
