An option is better than a pipe
a) in a perl script, a pipe force system to use sh -c
instead exec/fork
b) for aliases
alias fb='from -tcs owner-freebsd-security'
is simpler than [for bash]
fb () {
from -tcs owner-freebsd-security "$@" | wc -l
}
most people forget the "$@"

Look at your mailbox. All freebsd mailinglists have content-length.
$ egrep '^From ' *|wc -l
200
$ egrep '^content-length' *|wc -l
200
