The next line should show the connection: katgar:~ # telnet mx2.epicuria.be 25 Trying 204.200.196.67... Connected to mx2.epicuria.be. Escape character is '^]'. 220 leolargo.tempdomainname.com ESMTP Sendmail 8.13.1/8.12.6; Fri, 21 Jan 2005 17:46:40 +0100 (CET)

That is strange indeed. Your DNS seems to resolve the host to the correct ip address but is unable to receive the connection? What about pop3? katgar:~ # telnet mx2.epicuria.be 110 Trying 204.200.196.67... Connected to mx2.epicuria.be. Escape character is '^]'. +OK POP3 leolargo.tempdomainname.com 2004.87 server ready quit +OK Sayonara Connection closed by foreign host. katgar:~ # ping mx2.epicuria.be PING mx2.epicuria.be (204.200.196.67) 56(84) bytes of data. 64 bytes from leolargo.tempdomainname.com (204.200.196.67): icmp_seq=1 ttl=53 time=111 ms Is an icmp echo request with 'ping' really working?
what kind of problem could it be ? I can access mx2.epicuria.be 25 with all my email clients but postfix cannot access it ?!
Do you configure your email client on your mail server with mx2.epicuria.be as your smtp server and it works? This shouldn't be possible since the client is using the very same mechanism as we do with telnet on port 25. Sandy
