#55 rename after sendmail error

[Sami Farin]

If mixmaster fails to execute sendmail,
it renames the pool file so that you can't try to resend without manual rename.

in pool_dosend() I did this way:

if (msg_send(path) == 1)
mv(e->d_name, "msg");

original version renames to "err".
comments?

if sendmail runs out of mem, why shouldn't one be allowed to retry after a couple of seconds manually?

BTW. there's a bug in Redhat Fedora FC6 glibc-2.5-8 pclose(),
it returns 0 on success and 32512 (instead of -1) on failure (and does not set errno).
