I'd like to prevent people on the Net from using my sendmail as a relay mailer (i.e. to prevent the spread of spam) -- I only want them to be able to use it if they're sending mail to a user somewhere on my domain. Is there an easy way of doing this in sendmail (something I can add/change/delete in my sendmail.cf)? I'd really rather not have to switch to qmail or something like that, if I can avoid it.
