Qsmtp installation

Gentoo users

You have to use a portage overlay. Please read through the Gentoo documentation on how to set up layman correctly.
Add this overlay description file to the overlays entry the layman configuration (/etc/layman/layman.conf): https://opensource.sf-tec.de/portage-overlay.xml
Add the now available overlay:
```
layman -a dakon
```
You have to unmask this two packages, they are only available in ~arch. Your arch is something like x86 or x86-64 (I also successfully used this one on hppa, but there should be no problems on others archs).
```
echo dev-libs/libowfat >> /etc/portage/package.keywords
echo mail-mta/netqmail-Qsmtp >> /etc/portage/package.keywords
```
Now emerge Qsmtp:
```
emerge -at netqmail-Qsmtp
```
Normally you should get two packages, libowfat and qsmtp. If you don't have qmail installed already you will get tons more.

openSUSE

RPMs for newer openSUSE, SLE, RHEL, CentOS versions: in my openSUSE repository (graphical chooser)
RPM for openSUSE 11.3 x86_64: libowfat-0.28-2.x86_64.rpm (specfile)

all other versions:

cd /usr/src/packages/SOURCES
wget http://dl.fefe.de/libowfat-0.30.tar.xz
# put specfile from https://build.opensuse.org/package/show/home:DerDakon/libowfat into ../SPECS
rpmbuild --ba ../SPECS/libowfat.spec

Install other needed packages (the name of the OpenSSL package may be different in older versions):
```
zypper in libopenssl-devel cmake
```
Install notqmail: use the RPMs
Get and install Qsmtp:
```
cd /tmp
wget http://opensource.sf-tec.de/Qsmtp/Qsmtp-0.37.tar.xz
tar xJf Qsmtp-0.37.tar.xz
mkdir build
cd build
cmake -D CMAKE_INSTALL_PREFIX=/var/qmail ../Qsmtp-0.37
make install
```
You can switch on additional features like support for MD5 passwords in AUTH on the CMake command line, e. g. by passing "-DAUTHCRAM=On". Do not enable and use the CHUNKING option for Qsmtpd in any version prior to 0.34. It is entirely broken and can lead to endless loops (i. e. eating your CPU time) and scramble your mails. If the remote server is friendly and sends "good" data you may be lucky and actually get something that is closed to the content you want to, but even that is not entirely certain.

Now move the old qmail-remote out of the way and use Qremote instead:

mv /var/qmail/bin/qmail-remote /var/qmail/bin/qmail-remote.orig
ln -s /var/qmail/bin/Qremote /var/qmail/bin/qmail-remote

Congratulations, you are almost done. Now you need to decide how to control your daemons (i.e. using daemontools or traditional init scripts), install all other things you may need (vpopmail, ucspi-tcp, ...). Don't forget to setup the control files (call
```
/tmp/netqmail-1.06/config-fast $(hostname --fqdn)
```
for the basic settings). Read the usual qmail docs on what's next. My part is done here. Only make sure to call /var/qmail/bin/Qsmtpd from tcpserver instead of /var/qmail/bin/qmail-smtpd.

All others
