I'm using Ubuntu 6.06 behind IPCop. I forwarded the ports and i can send mail. I cannot receive mail nor login via e-mail client to mail.mydomain.tld (lookup fails) so i's a DNS problem. Which ip do has to be put in the DNS records? 192.168.0.2 or the real one from IPCop? Another thing.. mail.warn shows this: "database /etc/aliases.db is older then the source file /etc/aliases"
You must use a public IP address because otherwise nobody from outside your local network can access the domain. So don't use 192.168.0.2. Please run Code: newaliases /etc/init.d/postfix restart
