hello, I've a small LAN with a fedora core 3 (a machine called fedora3, 192.168.0.50, sendmail 8.13.1.2, dovecot 0.99.13-3) and a windows 2000 (a machine called zenone, 192.168.0.20) I've not still configured DNS on fedora, but I've so edited /etc/hosts: 127.0.0.1 localhost localhost.localdomain 192.168.0.50 fedora3 192.168.0.20 zenone I've made the same on windows and the 2 commands: ping zenone ping fedora3 works perfectly in both directions. For the sendmail side, I've made the following changes on the /etc/mail files: -added fedora3 on local-host-names -dnl # DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl in sendmail.mc reloaded the daemon, the telnet fedora3 (and localhost) on port 25 & 110 (sendmail & dovecot) is OK but sendmail daemon is really slow starting. giving the command newaliases from the shell sendmail tells me: WARNING: local host name (fedora3) is not qualified; see cf/README: WHO AM I? I've seen the README file (chapter WHO AM I?) but I've not understood good the explication: what should I add to (I think) my sendmail.mc file? thanks a lot in advance for your help, fabiano
