qmail-tcpto - print TCP timeout table
qmail-tcpto
After an SMTP connection attempt times out, qmail-remote
records the relevant IP address. If the same address
fails again, qmail-remote assumes that further attempts
will fail for at least another hour.
qmail-tcpto prints qmail-remote's current list of time-
outs.
qmail-tcpto must be run either as root or with user id
qmailr and group id qmail.
