In my /etc/hosts file exists a line with 127.0.0.1 resolving the default domain local hostname. It didn´t include the others locals domains hostname. I added those names.

Re: [qmailtoaster] DNS temporary failure (#4.3.0)
I have bind installed on the same machine, and it resolves some locals domains. When the link is down, It won´t accept mails to non-local domains, and that´s fine, (and obvious!). But the problem is that it doesn´t accept mail to local domains, resolved by my local bind server. First thing I checked was resolv.conf to make sure the server was consulting itself (and it was). I also tried eliminating /var/qmail/control/blacklists (and restarting qmail), and it was the same. Jake, I don´t understand hat do you mean by "you may need to make your machine (127.0.0.1) the first forwarder". Do you mean in resolv.conf or in named.conf? Isn´t that used when bind can´t resolv (non-local domains)? Salutti Natalio > It's trying to resolve the hostname to the IP, which it can't do if the > connection is down.
