Setting Connections (IIS 6.0)
A connection is initiated whenever a message is sent to or received from a remote server.
Note
Designating the TCP port that the SMTP service uses to receive incoming messages is done when you configure the Simple Mail Transfer Protocol (SMTP) virtual server.
Setting connection limits and imposing connection time-outs can make it more difficult for someone to initiate a malicious attack (such as denial of service) against your virtual server.
Important
You must be a member of the Administrators group on the local computer to perform the following procedure or procedures. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run IIS Manager as an administrator. At a command prompt, type runas /User:Administrative_AccountName "mmc systemroot\system32\inetsrv\iis.msc".
