Sometimes I'll receive a message with a header field where a

like to catch those in a recipe.
The problem is that the newline before a properly indented
continuation line in a header won't match procmail's $ or ^ (usually
that's a good thing).
* H ?? ? egrep '^[ ]+$' # egrep -x '[ ]+' if it groks -x
will do it, but is there a way within procmail without the external
program?
I don't think there is. AFAICT, Procmail unfolds the continuation
lines (presumably because the break points don't have any semantic
relevance), so the best you can do without calling an external program
is find out if there are trailing blanks.
