I have just installed postfix on one of my servers purely in order to get email output from cron jobs. I have installed postifx previously on other servers nad had no problems. But on this installation I found that no messages could be delivered because there was no aliases file. I was seeing this error in /var/log/maillog:
Sep 25 11:50:23 dmz postfix/local[17294]: fatal: open database /etc/aliases.db: No such file or directory Sep 25 11:50:24 dmz postfix/master[17267]: warning: process /usr/libexec/postfix/local pid 17294 exit status 1 Sep 25 11:50:24 dmz postfix/master[17267]: warning: /usr/libexec/postfix/local: bad command startup -- throttling The problem was that there was no aliases file created as part of the installation. I don't remember having to do this as part of previous installs, which I think may have been sendmail replacements and perhaps installing sendmail sets up aliases files so the problem never appeared. I ended up fixing the problem by running: # touch /etc/aliases # newaliases Shouldn't postfix create a default aliases file? Or at least include a sample one somewhere as part of the install?
