There are a few problem with that:
1 - it deletes all consecutive headers starting with an X that follow an
X-Spam header e.g. "X-Delivered-to"
2 - if the bottom header is deleted, the header-body separator is
also deleted
3 - ^X-Spam can match on the body causing part of it to be deleted, in
the worst case corrupting the mime structure.
I think the following is a bit more robust:
awk '
/^[^[:space:]]/ { remove = 0 }
/^X-Spam/ { remove = 1 }
/^$/ { isbody = 1 }
isbody || !remove { print }
'
