"localhost" needs to be resolved properly before this will work. What is the actual message you see? Does it work from a different machine? Do you have a firewall running? Does "netstat -an | grep 25" show port 25 as "LISTENING"? -- Joost

From: "Khawaja M. Jawad" on 9 Jun 2010 00:39 Thanks for the answer over a silly question J.Roeleveld. It was a firewall issue, I added rule for localhost to connect at port 25. Issue is resolved. -- Jawad -----Original Message----- From: owner-postfix-users(a)postfix.org [mailto:owner-postfix-users(a)postfix.org] On Behalf Of J.

Even though I have considered it myself as well once, I am curious as to why someone would put a firewall on localhost? -- Joost Roeleveld
