As a policy, authenticated SMTP helps cut down on folks sending SPAM and allows the ISP to track which account is sending what type of email content for further demographic study. While authenticated SMTP is good for the ISP, it is not a configuration supported <i>out of the box</i> by most Linux distributions. This means that all those system emails and log reports emailed by <i>root</i> never make it anywhere anymore.</p> <a href="http://www.howtoforge.net/exim-authenticated-smarthost" title="Read the rest of this posting." class="read-more">Read more...</a> Email Fri, 04 Jul 2008 17:57:02 +0200 http://www.howtoforge.net/exim-authenticated-smarthost http://www.howtoforge.net/exim-authenticated-smarthost#comment http://www.howtoforge.net/apache2-logging-to-a-mysql-database-with-mod_log_sql-on-debian-etch <p><b>Apache2: Logging To A MySQL Database With mod_log_sql (Debian Etch)</b></p> <p>This guide shows how you can write the Apache2 access log to a MySQL database instead of a file.
