Title: How to Limit the Number of Messages Sent in One Connection in SMTP Server in Windows Server 2003

Objective: The objective of this demo is to teach you how to limit the number of messages sent in one connection in SMTP server in Windows Server 2003. This option enables you to limit the number of messages sent in a single connection. It also provides a method to improve system performance by allowing the use of multiple connections to deliver messages to a remote domain. If you commonly send a large number of messages to certain remote domains, you could set the Limit number of messages per connection to value to a relatively small number, such as 20. As a result, when sending 100 messages in one session, the SMTP service immediately opens a new connection after the first 20 are sent, another after the next 20 are sent, and so on. In this case, there could be up to five simultaneous connections delivering queued messages to one destination. Message delivery would be faster because fewer messages are delivered simultaneously, instead of in one long stream over one connection.
