then
headers add "Old-Subject: $h_subject"
headers remove "Subject"
headers add "Subject: ***[SPAM]*** $h_old-subject"
headers remove "Old-Subject"
endif</blockquote>
<h3>3. In etc/exim/exim.conf after this line:</h3>
<blockquote># $Cambridge: exim/exim-src/src/configure.default,v 1.14 2009/10/16 07:46:13 tom Exp $</blockquote>

<blockquote>system_filter = /etc/exim/filters</blockquote>

<blockquote>#spamd_address = 127.0.0.1 783</blockquote>
with:
<blockquote>spamd_address = 127.0.0.1 783</blockquote>

<blockquote># Bypass SpamAssassin checks if the message is too large.
#
#accept condition = ${if >={$message_size}{100000} {1}}
#add_header = X-Spam-Note: SpamAssassin run bypassed due to message size
