Hello, I have two servers, both are running CentOS 7 and Exim 4.84. However, on one server the 'primary_hostname' is being returned as the hosts FQDN whereas on the other server it is returning just the short name. I have checked on both servers that things such as '/etc/resolv.conf' and '/etc/hosts' are correct (and basically the same), and that 'uname -n' returns the short name as does 'hostname', and 'hostname -f' returns the FQDN (on both servers).
I could set the primary_hostname on the servers but generally for our local servers we use the same exim.conf file which has nothing server-specific in it. The primary_hostname has been correctly calculated by Exim on all our CentOS 5 and 6 servers, but for some reason fails on this one CentOS 7 server. I have looked into this, but simply cannot see why one server gives the FQDN and the other does not. Both CentOS 7 servers have been set up the same. Does anyone have any ideas about this, or suggestions of things I could check? Thanks, John. -- ---------------------------------------------------- John Horne Tel: +44 (0)1752 587287 Plymouth University, UK -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
