Nearly every Unix based operating system that ships with a mail transport agent, ships with sendmail. Sendmail has been the defacto standard in MTA's for years. Until the last handful of years, there were few options; if you wanted to send and receive email, you used sendmail. Over the years, sendmail gained a reputation as being insecure. It was large and monolithic, and often operated with excessive privileges. This lead to a wide variety of vulnerabilities being found in sendmail. Sendmail security has improved dramatically in recent history, but its still based on the original design.
