I had the same exact problem with Red Hat 9.0 today(you can send mail locally, just not beyond your LAN, right?). I made several changes, but I think these were key(BTW, Red Hat was set on medium security): 1.) In the sendmail.mc, see where I first changed the Addr= from the loopback address? Apparently that is wrong, you should just comment it out:
dnl # The following allows relaying if the user authenticates, and disallows dnl # plaintext authentication (PLAIN/LOGIN) on non-TLS links dnl # define(`confAUTH_OPTIONS', `A p')dnl dnl # The following causes sendmail to only listen on the IPv4 loopback address dnl # 127.0.0.1 and not on any other network devices. Remove the loopback dnl # address restriction to accept email from the internet or intranet. dnl # address restriction to accept email from the internet or intranet. dnl # DAEMON_OPTIONS(`Port=smtp,Addr=64.163.109.75, Name=MTA') 2.) That removed the original error, and replaced it with a RELAY error, so I added an entry in the /etc/mail/access file: [EMAIL PROTECTED] mail]# vi access # 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 RELAY localhost RELAY 127.0.0.1 RELAY 192.168.0. RELAY 3.) But look at this segment in sendmail.cf: [EMAIL PROTECTED] mail]# vi sendmail.cf # Hosts for which relaying is permitted ($=R) FR-o /etc/mail/relay-domains That prompted me to create a relay-domains file with my local network(192.168.0.) which seemed to clear up the problem. If any of these settings are bad from a security standpoint, please, anyone suggest something better!
