No, that is not the cause. $ echo -e "Subject: Foo\n" | ./spamassassin | grep Subject Subject: [SPAM] Foo X-Spam-Prev-Subject: Foo $ cat rules/99_DEVEL.cf required_score -999 # regardless of score, classify spam # to enforce header rewriting clear_headers rewrite_header Subject [SPAM] Besides, your own reply to my first post to this thread on Mon also shows this claim to be false. The output of the command I asked you to run clearly shows clear_headers in your config being in effect and a rewritten Subject. -- char *t="\10pse\0r\0dtu\0.@ghno\x4e\xc8\x79\xf4\xab\x51\x8a\x10\xf4\xf4\xc4"; main(){ char h,m=h=*t++,*x=t+2*h,c,i,l=*x,s=0; for (i=0;i<l;i++){ i%8? c<<=1: (c=*++x); c&128 && (s+=h); if (!(h>>=1)||!t[s+h]){ putchar(t[s]);h=m;s=0; }}}
