Although the term SMTP AUTH is typically used in the context you have
described above... sendmail can also be configured to authenticate as a
client to another MTA (like your ISP's mail server). This is typically
done by defining a "smarthost" in sendmail.mc and then adding your
authentication tokens (realm, user, pass, auth mechanisms) to either
/etc/mail/access or creating your own /etc/mail/authinfo file along with
adding FEATURE(`authinfo')dnl to sendmail.mc.
