Ask your administrator choose your account, select Forwarding: NotifyMail to.... Then have your administrator enter your IP address or DNS name in the space provided OR select Forwarding: NotifyMail to last IP. The latter method is preferred as you can change machines without your administrator having to make a modification to the server. In order for EIMS to notify you using the latter method, you must check your mail (using your email client) at least once.
When configuring NotifyMail, make sure the TCP port is set to 79
Below is a screenshot from EIMS (1.3) showing the configuration.
