Laconica and Postfix on Ubuntu

05 Feb 2009

Recently at work we tried to deploy which is a microblogging platform. We wanted to do this for 2 reasons. The first being the obvious, which is to be able to have a campus wide microblogging platform. The second, and what I think is the coolest, is that we wanted to use it to post our nagios alerts for our systems. Each monitored server will post its alerts to its own account on and admins can subscribe themselves to whichever servers they see fit.

Now for the technical aspect of jumping the Postfix barrier to get the email submission to work. In the documentation for it says to simply put the following into your /etc/aliases file


Well this is wrong for 2 reasons. First of all the syntax is incorrect. You need a symbol before the script to say that you are piping the email to a command. The second reason which causes the most problems is the fact that /etc/aliases does not support the * wildcard on Ubuntu if at all. Its a security hole I guess. Here is how to work around this issue.

edit/create /etc/postfix/virtual and make sure this line is in there

@ laconica

then run

sudo postmap /etc/postfix/virtual

to compile the file for postfix to use

Now edit /etc/aliases and put this line in there


make sure that the maildaemon.php is executable

chmod 755

then run

sudo newaliases

now restart postfix just for a good time

sudo /etc/init.d/postfix restart

Alright you should be able to send emails to the random mail address that assigns to the user accounts under their profiles. Don’t make the same mistake I did and try to send an email from a different address than the one you registered your account with though, it won’t work :)
