[bitfolk] SpamAssassin with exim4 on Ubuntu

Hello, Spam to my e-mail address has recently exceeded my tollerance level and I am now looking in to implementing spam checking, I am however having some trouble configuring exim4 to use the BitFolk shared SpamAssassin service. Currently I have done the following in attempting to configure my mail server to use SpamAssassin, per the documentation at [1]: - Replace exim4-daemon-light with exim4-daemon-heavy - Add "spamd_address = 212.13.194.5 783" to /etc/exim4/exim4.conf.template. - `update-exim4.conf -v` (this indicates /etc/exim4/exim4.conf.template is used). - `/etc/init.d/exim4 restart` I then send a test message via a foreign mailserver I have access to, however no spam checks are made. I checked /var/log/exim4/maillog and it does not show any references to attempting to contact a spamd server. Does anyone have any pointers regarding how I can troubleshoot this, or anything I am doing wrong? Thank you, [1] http://www.exim.org/exim-html-4.68/doc/html/spec_html/ch41.html#SECTscanspa… -- Robert Leverington http://rhl.me.uk/
