I have sendmail running under the default configuration to listen on port 25 and only accept mail from localhost. However, I would like to configure it to only be able to send mail to localhost. I basically don't want mail going off the machine. This is only being used for internal email. TIA. in /etc/mail/access is a list of domains, machines, and/or networks that sendmail will accept, reject, or relay mail for. so, to accept mail from machines and on your net and localhost rather than relay, use OK instead of RELAY i.e # Check the /usr/share/doc/sendmail/README.cf file for a description # of the format of this file. (search for access_db in that file) # The /usr/share/doc/sendmail/README.cf is part of the sendmail-doc # package. # # by default we allow relaying from localhost... localhost.localdomain OK localhost OK 127.0.0.1 OK yourdomain.com OK the last entry assumes you have dns set up for your lan (with an appropriate MX record) after editing the fail do a "make restart" from /etc/mail -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
