The Problem
Hi everyone.
If you followed my
Postfix tutorials so far, some of you might have notices that despite it is not possible to use our mail setup as a malicious spam relay, it is still possible to spoof local addresses and send emails to another local address.
This looks like this:

Connected to wthack.de.

It has been a while since i wrote my last entry, but after some public demand i decided to write something about
DSPAM and
Postfix.
To fight the massive amount of spam nowadays it has become critical to filter your email accounts with certain techniques to separate the spam and the ham.
As my current server is very low on resources, i was unable to use the usual suspect

So i had to look out for some alternatives and found DSPAM, which is the work of Jonathan ...
Today i set up a network wide pulseaudio server for my home. The main obstacle was to not use the system-wide mode which was highly discouraged by the pulseaudio team and not available on my gentoo powerpc installation anyways. I assume that you have a already working pulseaudio setup an pulse resolves your alsa sinks correctly.
First step of course is to install the required packages. I used the following useflags:
media-sound/pulseaudio avahi dbus
net-dns/avahi dbus
sudo paludis -i pulseaudio avahi
Create a user to run the pulseaudio process and give him the appropriate rights:

Some days ago, i played a few hours with my Sony Ericsson W595 and discovered it's remote control function. I figured out an easy way to use this mode to remote control my mplayer while playing a video, so i am able to use the basic mplayer functions while lying on my bed. At first, you have to choose an application that actually enables your computer to be remote controlled. As i am using gentoo linux on my main computer, i used net-wireless/gnome-bluetooth. On ubuntu this should be preinstalled already.
Connect the phone
The first step is to bind your ...
After describing how to set up a postfix which delivers the mails to your local maildir, i am now going to explain how to set up
dovecot to export your local maildir with
IMAP and
SSL/TLS.
At first, we have to install the necessary ubuntu packages:
sudo apt-get install dovecot-imapd
After installing dovecot, we have to edit the dovecot config file. This is really straight forward and you only have to edit one single line in your /etc/dovecot/dovecot.conf :
mail_location = maildir:~/Mail
Please change the maildir path to your needs. If you would like to combine my smtp and ...
