I was wrong in my first assessment. Mail that gets an X-Warning: header
does not get copied by the system-filter at all. Here is a log sample:
2002-08-04 14:06:31 H=(qqhrmc.net.cn) [61.138.3.251] Warning: found in bl.
spamcop.net
2002-08-04 14:06:32 H0C7YV-0001JU-00 <= 104034.1703urj@???
H=(qqhrmc.net.cn) [61.138.3.251] P=esmtp S=7908 id=200208042157.FAA25978@q

2002-08-04 14:06:32 H0C7YV-0001JU-00 => spam <system-filter> R=localuser T=
local_delivery
2002-08-04 14:06:32 H0C7YV-0001JU-00 Completed
I'm guessing that this is because of the "if first_delivery then" clause in
my system-filter. Does that make sense?
