Sendmail on Linux II -- the sequel -- I FIGURED IT OUT

Post #25,752 by clkennedy 1/25/02 3:55:10 PM 2/1/02 6:14:16 PM Reply	Sendmail on Linux II -- the sequel -- I FIGURED IT OUT SEE MY OWN REPLY TO THIS MESSAGE It's unanimous -- sendmail is a beast and I should use something else. The problem is that for a variety of reasons I need to continue on this path using sendmail. I got the outbound mail working OK -- It was only looking at the loopback device. Now I have the inbound to contend with. Below are excerpts from the logs generated at my ISP and the log generated by sendmail. Anybody got any Ideas?

Post #26,111 by boxley 1/28/02 3:45:15 PM Reply	you are getting an access denied message which means either you or the isp are not receiving at this time. Now the ISP depending on how you are testing inbound might think it is a email relayer. For example when I was with the FAA in Alaska email outbound from our desks went thru a proxy to outside addresses that were being returned as undeliverable the ISP had a rule setup that proxied email was probably relay mail (spam) and would refuse to forward to the rest of the world. thanx, bill My Dreams aren't as empty as my conscience seems to be

I logged into the smtp service using telnet. using: telnet localhost 25 -- everything worked fine. using: telnet xyz.com 25 -- I got 550 5.0.0 Access denied when I did anything. The problem -- I hadn't removed the /etc/hosts.allow & /etc/hosts.deny files. Once I did it happily talked to any host that wanted to send me mail. Duh !! Cliff Kennedy
