Ubuntu: Sending e-mails with Rails + exim4 (for Redmine)

I have encountered a problem with redmine sending out emails without a "to" recipient.

To fix that, edit the file /etc/exim4/exim4.conf.template to include the line

extract_addresses_remove_arguments = false

and run

sudo dpkg-reconfigure exim4-config

to re-generate the config.

You need to have exim4 to not-splitted config files, afaik.
