OK, I think I've figured it out. Its to do with the way sendmail treats hostnames. When you install RH9, it asks you for a hostname which the installer writes into /etc/sysconfig/network and /etc/hosts The entry into /etc/hosts seems to confuse sendmail. Removing the entry containing the hostname allows sendmail to work. Eg. If you called your machine rh9box on install, you'll have the following in your /etc/hosts file 127.0.0.1 rh9box localhost.localdomain localhost This should read 127.0.0.1 localhost for sendmail to work. Now the question is does anything else break when you change it? Looks like a config problem, closing bug. Florian La Roche Of course its a config problem. My point was that it was a config problem introduced by the Redhat Installer. i.e. the installer disables sendmail's ability to send mail. Which kind of negates its purpose. Anyway, I've done my duty reporting it. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030529 Description of problem: After installing redhat 9, I am unable to send mail. Using eg. mail -s "test mail" bob will result in the mail sitting in the queue with the message "no route to host". This would initially seem like a DNS issue, however dig can get all the information on any domain, including MX information. Any website is browsable. I have tried this on three separate, successive installations of RedHat 9. The security settings are medium, and SMTP is allowed. I have tried uninstalling sendmail and re-installing I have tried altering the following sendmail settings - SMART_HOST - Masquerade by editing sendmail.mc and running m4 to generate a new configuration. I have tried sending mail from pine, first altering the configuration so that it sends via my ISP's SMTP server. This also fails. Other computers on the same network segment can send mail, so the ISP is not blocking port 25. Version-Release number of selected component (if applicable): 8.12.8-5.90 How reproducible: Always Steps to Reproduce: 1. Install redhat 2. Try to send mail Actual Results: mail is not sent Additional info: I can't imagine this is a widespread bug, or else everyone would have complained about it. I think it must therefore be something specific to my configuration, although I can't think what.
