Title: How to Set Recipient Limits in SMTP Server in Windows Server 2003

Objective: The objective of this demo is to teach you how to set recipient limits in SMTP server in Windows Server 2003. You can determine the maximum number of recipients for a single message sent in one connection. The default is 100, which is the minimum number specified in Request for Comment (RFC) 821. Many clients return messages with a non-delivery report (NDR) after an error message is received, indicating that the maximum number of recipients has been exceeded. The SMTP service does not return messages in this instance. It opens a new connection immediately and processes the remaining recipients. For example, if the recipient limit is set to 100 and a message with 105 recipients is received, the first 100 are delivered in one connection. Then, a new connection is opened, and the message is processed for the remaining five recipients.
