Because the ":\b" is nonsense. Unless the colon is immediately followed
by a "word" character (\w), "\b" can't possibly match since the colon
is a "non-word" character (\W) and thus there is no transition, i.e.
no "(\w\W||W\w)". To say it another way, "\b" is only meaningful at
the boundary between "word" and "non-word" characters. The first regex
should be written as:
/^subject:\s*RCPT:/i
Here's the sample.cf patch (output line numbers assume 1.94.1 patches):
