I normally use an awk script for this sort of job because they are
short, easy to write and run fast.
Here's one I use to remove SA headers from the messages I keep as an SA
test corpus. Its part of a larger, site-specific, shell script. Much of
its apparent complexity is because its capable of deleting multi-line
SA headers and because it recognises the blank line following the
headers and switches into a pure copy mode at that point.

}
/^[A-Za-z]/ { act = "copy" }

/^$/ { body = "yes"; }

if (act == "copy" || body == "yes")
{ print }
}

If you don't know awk, and the mere fact of you asking this question
suggests you don't, I strongly suggest you get hold of the O'Reilly
"Sed & Awk" book and learn how to write awk scripts because you're
likely to find all sorts of uses for awk once you know it.
