Hi there. I installed postfix on a Ubuntu Dapper install and use ISPConfig to manage things. I've configured my system and postfix with a hostname that isn't currently usable (e.g. the domain is currently set to another ip). I've edited main.cf and set myhostname to localhost. But everytime a mail comes in postfix tries to deliver it to [email protected]. I've restarted postfix, but that didn't help. Any ideas? This is my /etc/postfix/main.cf: http://paste.ubuntu-nl.org/15267/ And these are the messages i get in mail.log: Apr 12 22:26:58 localhost postfix/smtp: connect to ubuntu606m.worldofubuntu.com[220.127.116.11]: Connection timed out (port 25) Apr 12 22:26:58 localhost postfix/smtp: A3EAB6E837F: to=<[email protected][email protected] ubuntu606m.worldofubuntu.com is the address i used as a hostname in /etc/hosts and /etc/postfix/main.cf as myhostname. The address is currently not yet running in this server. What am i missing here?
