adding
enable_starttls_auto: :true
to
/etc/redmine/default/email.yml
has fixed my problem

wget "http://download.mozilla.org/?product=firefox-3.6&os=linux&lang=en-US"

tar xvjf firefox-*.bz2

sudo cp -r firefox /usr/lib/firefox-3.6

sudo mv /usr/bin/firefox /usr/bin/firefox.old
sudo ln -s /usr/lib/firefox-3.6/firefox /usr/bin/firefox-3.6
sudo ln -s /usr/bin/firefox-3.6 /usr/bin/firefox

sudo /etc/init.d/squid restart

sudo service squid restart

sudo service squid start

sudo service squid stop

Shame on me, I know :) It is just for a copy-past.

sudo /etc/init.d/apache2 restart

sudo EDITOR=nano crontab -e

I use small instance. My solution needs near 900MB of memory so micro instance will not work.
