sendmail 8.9 open relay
 

Hi,

ordb.org says one of my servers is an open relay. What is the best way to close it? I am running sendmail 8.9 on a redhat 6.2 box

either turn off SMTP altogether or set up your allowed relay domains. This could be done easily using Webmin or editing the relay-domains file and adding the allowed domain(s), i.e. abc.com
