Hi,

I went on to get evolution's source code and after compiling it myself
and verifying that SpamAssassin and BogoFilter support are enabled I
dug into the code and decided to comment these two lines out:

if (!e_mail_junk_filter_available (junk_filter))
                        g_queue_push_tail (&trash, link);

They can be found in e-mail-session.c, method
e_mail_session_get_available_junk_filters. After compiling evolution
again and starting it, I finally had the dropdownbox with both
bogofilter and spamassassin available. When I tried to use SpamAssassin
evolution told me, upon selecting the first e-mail as spam, that
/usr/bin/sa-learn was nowhere to be found. Which is correct, in
ArchLinux it's apparently in /usr/bin/vendor_perl/sa-learn. I'm really
not sure who is correct here but to fix it for me I used ln -s to link
sa-learn to /usr/bin and got a working spam filter immediately.

As for bogofilter: It works without any problems. No bugs or anything,
just has a lousy spam detection rate.

Could someone verify wether the dropdownbox is displayed if only one
(either spamassassin or bogofilter) junkfilter is installed? If that's
the case someone should change that. What if someone has bogofilter
installed but doesn't want to use it in Evolution?

With kind regards
Steffen Winkler
