Obviously the Mail Transfer Agent must be running in order to send e-mail messages locally or to external mail server (like myseneca.ca). In this section, we will determine information relating to Seneca College's MTA when email messages are sent via your VM2 machine.

Normally, email headers are seldom seen with our e-mail applications such as web-mail, MS Outlook, or Thunderbird. There are way in order to view detailed header information for each email we send that provides information how the email message was sent, including the name of the program that is running as the Mail Transfer Agent and its IPADDR. Although these email headers may look complicated, they can trace the steps of sending the e-mail messages among the MTAs to gain a better understanding of the email transmission process.
