It seems that you think it is a problem if people can connect to your
machine on port 25 and send email to your users. That's how SMTP works. If
you don't allow it, then you can't get email delivered to you from the
Internet.
If you don't want to accept email from the Internet, then delete everything
except:
acl_check_rcpt:
accept hosts = :
accept hosts = +relay_from_hosts
accept authenticated = *
deny message = relay not permitted
If you want to accept email from the Internet, but not spam, then you have
to use a variety of anti-spam techniques. None of them are perfect, and
there are too many to describe here.
