Post subject:  POP3 server failed (Postfix, Dovecot, MySQL on Ubuntu)

I did install Email with Postfix, Dovecot and MySQL on Ubuntu 10.04 LTS (Lucid)
http://library.linode.com/email/postfix/dovecot-mysql-ubuntu-10.04-lucid#sph_more-information

Last entries:
chgrp vmail /etc/dovecot/dovecot.conf
chmod g+r /etc/dovecot/dovecot.conf

Then the POP3 server failed:
telnet localhost pop3

Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

How can I solve the issue?

If you run cat /etc/*release I think you'll find that you're using Ubuntu 12.04, not 10.04. Differences between the releases mean you can't follow the Library article verbatim.

I will restore my backup to the point of the LAMP server installation. Can you recommend a stack that installs everything at ones needed for a complete mail server?

I installed the mail server new and tried now the setup: https://mail.example.com/postfixadmin/setup.php

I receive this error: Secure Connection Failed
Error code: ssl_error_rx_record_too_long

I checked: Listen 443 https, look OK.

What can trigger this problem or did I miss something?
