[Hostname] console login: May 31 15:25:42 [Hostname] sendmail[295]: My unqualified host name (Hostname) unknow n; sleeping for retry I get this message, when solaris starts up! Can somebody help me?? Greetz Holger

Well, I'll take a crack at it if you'll bear with me. I am by no means a sendmail expert. The unqualified host name means that sendmail is trying to use a host name that is ~not recognized~ - most likely because the domain needs appended to the host name. In your /etc/hosts file you will need to add an alias for the localhost that looks like: name name.subdomain2.subdomain1.... alias1 alias2 aliasX (note that that should all be on one line!) where is the ip address for the host, name is the name as recognized in your domain, name.subdomain1.subdomain2 is something like myname.cs.learn.edu where would be either one of edu,com,gov or any country code extension. Note that there is a trailing dot after the qualified host name. The alias1 and alias2 are the aliases for the host. The first alias you just setup is what sendmail will use as the qualified host name. To check to see if the name you tried to use is something that sendmail understands you can have sendmail tell you what to put there. You want $j from: /usr/lib/sendmail -d0.1 < /dev/null Then if you are running NIS or NIS+ you need to update that information and then restart sendmail: /etc/init.d/sendmail stop /etc/init.d/sendmail start WARNING: I have not got this to work but its worth a try. Good luck.

If you're not running sendmail on your machine then disable sendmail. Just rename the sendmail start up script. You can find the start up scrip is /etc/S88sendmail, rename to disable.S88sendmail. That way you won't have to run /etc/init.d/sendmail stop every time you bring up your machine. -arielc
