Hello, can anyone help a linux newbie? Thank you very much. I am a teacher trying to set up an email server for my school. I am on page 3 of the tutorial and I am pretty sure I have setup something wrong. Can anyone spot something wrong here? I am getting the following output from netstat -tap: Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 regents-pattaya.a:10024 *:* LISTEN 11158/amavisd (mast tcp 0 0 regents-pattaya.a:mysql *:* LISTEN 937/mysqld tcp 0 0 regents-patt:submission *:* LISTEN 1782/sendmail: MTA: tcp 0 0 *:5900 *:* LISTEN 11329/vino-server tcp 0 0 *:webmin *:* LISTEN 1912/perl tcp 0 0 *:www *:* LISTEN 1869/apache2 tcp 0 0 *:ssh *:* LISTEN 22783/sshd tcp 0 0 regents-pattaya.ac.:ipp *:* LISTEN 12635/cupsd tcp 0 0 regents-pattaya.ac:smtp *:* LISTEN 1782/sendmail: MTA: tcp 0 0 regents-pattaya.ac:smtp regents-pattaya.a:56017 TIME_WAIT - tcp 0 0 regents-pattaya.ac:5900 202.149.116.20:3073 ESTABLISHED 11329/vino-server tcp6 0 0 [::]:imaps [::]:* LISTEN 9783/couriertcpd tcp6 0 0 [::]op3s [::]:* LISTEN 9843/couriertcpd tcp6 0 0 [::]:5900 [::]:* LISTEN 11329/vino-server tcp6 0 0 [::]op3 [::]:* LISTEN 9810/couriertcpd tcp6 0 0 [::]:imap2 [::]:* LISTEN 9750/couriertcpd tcp6 0 0 [::]:ssh [::]:* LISTEN 22783/sshd tcp6 0 0 ubuntu:ipp [::]:* LISTEN 12635/cupsd I am also getting the following output from the command 'ehlo localhost' when using telnet 25: root@regents-pattaya:/usr/local/sbin# telnet localhost 25 Trying ::1...

Thanks Falko. I seem to have both packages installed. If I uninstall and remove Sendmail would that then solve the problem? I do have Postfix installed and have followed all the configuration steps in your brilliant howto. I am desperate to get this to work. I teach Information Technology at an International School - the IT Technicians are telling me it's impossible to set up a mail server on our Ubuntu server without buying something like Microsoft Exchange but I'd love to prove them wrong.
