====== Exim4 - Configure SASL ======

To configure **saslauthd** to provide authentication for Exim4.

SASL can be used when Exim is supporting local user email accounts.

The first step is to install the sasl2-bin package from the Main repository.

<code bash>
sudo apt-get install sasl2-bin
</code>

Edit the /etc/default/saslauthd configuration file and set START=no to:

<file bash /etc/default/saslauthd>
START=yes
</file>

Next the Debian-exim user needs to be part of the sasl group in order for Exim4 to use the saslauthd service:

<code bash>
sudo adduser Debian-exim sasl
</code>

Now start the saslauthd service:

<code bash>
sudo /etc/init.d/saslauthd start
</code>

Exim4 is now configured with SMTP AUTH using TLS and SASL authentication.
