The term given to the basic functionality of email being sent from one point to another, via the internet. Sendmail is often used by web scripts like contact forms, to send data automatically via an email server to another email address where no custom email rules have been created (i.e- the customer has not specified any SMTP or POP3 mail server settings to handle the email).
