Hi Andy
What is your hostname on that box? cat /etc/sysconfig/network
h0st.d0main.tld It seems as if 'h0st' is being dropped and replaced by 'localhost' to render: user@xxxxxxxxxxxxxxxxxxxx I'm looking to achieve: user@xxxxxxxxxx ~ /usr/sbin/postconf -n reports: ... inet_interfaces = all ... mydestination = $mydomain mydomain = d0main.tld myhostname = h0st.d0main.tld mynetworks_style = subnet myorigin = $mydomain ...
