Very simple fake email that hits both examples of this bug.
Header rules concatenate all headers into one block.
I have two examples that hit it since I couldn't fully replicate the real-world
example in a simpler test example.
Example bug.cf
########
# example (couldn't figure out how to skip the /s)
header BUG_IN_HEADER Received =~ /(by.*by)/s
describe BUG_IN_HEADER Should almost never fire but almost always does
score BUG_IN_HEADER 0.001
# real-world example, from my khop-general channel
header KHOP_2IPS_RCVD Received =~
/[\[\(\s]((?:[12]?\d\d?\.){3}[12]?\d\d?)[\[\(\s][^\[]*\[(?!\1)\d/
describe KHOP_2IPS_RCVD Received: Relay identifies itself as wrong IP
score KHOP_2IPS_RCVD 1.25 # 20050729
