Hi folks, Continued on "The Perfect Setup - Ubuntu Feisty Fawn (Ubuntu 7.04) - Page 5" http://www.howtoforge.com/perfect_setup_ubuntu704_p5 All went through w/o major problem unitl coming to "telnet localhost 25". I copy/paste the commands on the "Howto" to proceed. Please help me to clarify following points 1) On running; Code: # postconf -e 'smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination' I replaced "permit_mynetworks" with "permit_eth0". Did I make a mistake here? I have only one NIC on this PC 2) On running; # openssl genrsa -des3 -rand /etc/hosts -out smtpd.key 1024 Code: 284 semi-random bytes loaded Generating RSA private key, 1024 bit long modulus .........++++++ .............++++++ e is 65537 (0x10001) Enter pass phrase for smtpd.key:1024 [Enter] Verifying - Enter pass phrase for smtpd.key:1024[Enter] I use the same smtpd.key number "1024". Can I use different number? Coming to "telnet localhost 25" # telnet localhost 25 Code: Trying 127.0.0.1... telnet: Unable to connect to remote host: Connection timed out The firewall blocks it. # iptables -F # cat /etc/rc.local | grep 127.0.0.1 Code: iptables -I OUTPUT 3 -j REJECT -s 127.0.0.1 --reject-with icmp-port-unreachable # telnet localhost 25 Code: Trying 127.0.0.1... Connected to localhost.localdomain. Escape character is '^]'. 220 server1.example.com ESMTP Postfix (Ubuntu) ehlo localhost (hanging here) quit Connection closed by foreign host. "server1.example.com" has not been changed to "ubuntu.xyz.com". Where shall I check and how to fix the problem? TIA Edit-1 : ==== Hi Falko, I have finished up to section:- "18 Synchronize the System Clock" without problem. Your HOWTO works perfect. Wonderful!!! Thanks. If NOT installing ISPConfig, do I need proceeding section:- 19 Install Some Perl Modules Needed By SpamAssassin (Comes With ISPConfig) ??? Edit-2 (to fix above problem) : ==== Re-run following steps; # postconf -e 'myhostname = ubuntu.xyz.com' no printout (Remark: Previously I ran; # postconf -e 'myhostname = server1.example.com' ) # /etc/init.d/postfix restart Code: * Stopping Postfix Mail Transport Agent postfix [ OK ] * Starting Postfix Mail Transport Agent postfix [ OK ] # iptables -F # telnet localhost 25 Code: Trying 127.0.0.1...
