A UNIX server is used as the primary gateway to transmit mail out of the system to the Internet through SMTP. This Internet gateway was based in UNIX due to the deployment of an e-mail system before MS Exchange was commercially available. This machine needs to be monitored in order to ensure that e-mail can leave and enter the company. A failure in this gateway will not affect intra-company mail services. Aside from monitoring port #25 (see below), it is also necessary to monitor the operating system on which this service resides to ensure machine availability.

Severity definition:

1. = High priority, notify immediately;
