Postfix SMTP AUTH support for relayhost

Posted by on September 6, 2005 5 comments

Tonight I changed my relayhost for my outgoing home mail server to one that requires me to use SMTP AUTH so I needed to modify my main.cf on the outgoing server as follows.

Added the following settings to /etc/postfix/main.cf:
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options =

Create /etc/postfix/sasl_passwd as follows:
my.mail.relay.net username:password

Because the password is in cleartext make it root only:
# chown root:root /etc/postfix/sasl_passwd && chmod 600 /etc/postfix/sasl_passwd

Create the hash file:
# postmap /etc/postfix/sasl_passwd

Make the hash file world readable:
# chmod 644 /etc/postfix/sasl_passwd

Reload the Postfix config:
# /etc/init.d/postfix reload

2002 National Public Radio Documentary on New Orleans Hurricane Threat

Posted by on September 1, 2005 Comments Off on 2002 National Public Radio Documentary on New Orleans Hurricane Threat

I found something the other day which I found very interesting to hear so I’ll share it with you. In 2002 American RadioWorks (NPR) recorded a documentary called Nature’s Revenge: Lousiana’s Vanishing Wetlands. The fourth and final part of that series was about the possibility of a hurricane hitting New Orleans. Even at that time there were some very serious concerns by scientists stating what would happen with a near hit by a powerful storm. Of course we can now see that much of what they predicted can and is coming true. I think we’re going to see some serious questions raised in the coming weeks and months about why we were as unprepared as we were with this clearly documented risk and what we should do now with the problem that is New Orleans.

The audio from this story is still availible. If you have Real Player installed you can hear it by clicking this link. It’s only about twenty minutes long and I found it quite interesting to listen to earlier this week so I encourage you to listen if you get the chance. When listening remember that this was done three years ago!
