To quote the manpage for qmail-tcpto:
After an SMTP connection attempt times out, qmail-remote
records the relevant IP address. If the same address fails
again (after at least two minutes with no intervening suc-
cessful connections), qmail-remote assumes that further
attempts will fail for at least another hour.
Thus, since your firewall was down for ten minutes, qmail would
assume that it was going to be down for quite some time and stop
hammering on it.
If you want to clear the list of timeouts, so that qmail-remote stops
making that assumption, you can do that by running
/var/qmail/bin/qmail-tcpok.
