Erm... since I'm playing regex police anyway: nope. First,
\s includes \r and \n, so the first rule already included newlines.
If you want to only allow whitespace you'd have to specify
[ \t] or \p{IsSpace} or [[:blank:]], except that the latter two
match 24 and 16 other characters, respectively, including UTF-8
characters like U+180e, the mongolian vowel separator, and
U+202f, the narrow no-break space.
Second... you effectively built "BODY_IS_JUST_DIGITS_OR_WHITESPACE"
~~
Since [\s\d] will match either whitespace or digit, your rule will
also match lines containing only whitespace, and since whitespace
includes newline, it will match a "line" consisting only of "\n",
which appears in every email...
If you want to match a line containing digits and optionally
whitespace, use:
/^ \s* \d [\s\d]* $/x
And last but not least: matching newlines on body rules is useless,
since spamassassin removes line breaks before matching body rules.
It might leave the last newline present, for each paragraph that
it matches. I haven't tested that. But the trailing "$" on a regex
matches at the end of string, or it matches before the final \n
at the end of the string, so there's no need to consider newlines
for body rules at all.
