minimal dovecot.conf for Ubuntu, Centos, and Debian

November 15, 2010 Leave a comment

Here is a minimal doveconf for Ubutnu Maverick. It includes sasl. This also works for Debian including squeeze, and Centos. Debian and Centos use dovecot.pem for both ssl_cert_file and ssl_key_file.

protocols = imaps pop3 pop3s imap
mail_privileged_group = mail
disable_plaintext_auth = no
ssl_cert_file = /etc/ssl/certs/dovecot.pem
ssl_key_file = /etc/ssl/private/dovecot.key
auth default {
mechanisms = plain login
passdb pam {
userdb passwd {
socket listen {
client {
path = /var/spool/postfix/private/auth
mode = 0660
user = postfix
group = postfix

If you get this error with Ubuntu Maverick (10.10) either desktop or server edition
you can correct it like this:
edit /etc/initramfs-tools/initramfs.conf
and change MODULES=most to MODULES=dep
Then dpkg-reconfigure initramfs-tools
reboot and you should not see the error.

Ubuntu tasksel

November 5, 2010 Leave a comment

Renewing my experience with Ubuntu led me to try out the tasksel command. This is a very powerful utility (just apt-get install tasksel) to activate.

With tasksel you can configure your system for almost any function such as basic server, lamp server, cloud server, virtual host, etc. Try it you will like it!
