I followed Falko's howto for a perfect Mandriva-Server Now I have a problem: I can configure my mailserver in thunderbird, but I can't send any mails to it. First I got responses from my server, that "localhost.oli-home.de" couldn't be found, no wonder, since the domain doesn't really exist. Now I changed the line Code: postconf -e 'mydestination = /etc/postfix/local-host-names, localhost.oli-home.de' to Code: postconf -e 'mydestination = /etc/postfix/local-host-names, deneb.oli-home.de' in the howto and restarted postfix. Now I don't get any return-mails from my server any more, but the mail doesn't appear in my mailbox either! What can I do?
