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:

I am also getting the following output from the command 'ehlo localhost' when using telnet 25:

Thanks for your help,

You are using Sendmail instead of Postfix.

[matiancai74]

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.

Yes, uninstalling Sendmail would help. Make sure you start Postfix afterwards.
