I need to be able to send email from local user to a local user on my laptop (via logrotate), and I figured I need to have sendmail running for that to work. My question is, how is it set up by default? I want it to be virtually invisible, or at least inaccessible from the outside. Is that the default sendmail configuration?
Nevermind, found this in sendmail docs:

By default, the sendmail configuration files do not permit mail relaying (that is, accepting mail from outside your local host (class {w}) and sending it to another host than your local host).
