I followed the installation manual on Ubuntu site and everything looks all right except one tiny thing: I can’t send email using Telnet. Here is the response:</p> <pre>421 4.3.0 collect: Cannot write ./dfnBA9gfVO030273 (bfcommit, uid=0, gid=111): No such file or directory</pre> <p>I googled for an answer, but nothing useful came up so I tried to debug the problem myself. By looking into mail logs (/var/log/mail.log, found by examining /etc/syslog.conf) I found following strange response: </p> <pre> start postfix/master[15758]: fatal: bind 0.0.0.0 port 25: Address already in use</pre> <p>That means only one thing: there is another process listening on this port. Hmm, what could it be? Sendmail, perhaps. I uninstalled it, according to guides I was using, but it was still running.</p> <p>It’s time to stop it and start postfix!</p> <pre>sudo service sendmail stop sudo service postfix restart</pre> <p> </p> <p>Problem solved!</p> <p></p></body></html>http://blog.yellowbluebus.com/posts/wordpress20091210problem-testing-postfix.htmlThu, 10 Dec 2009 10:16:44 GMT
