qmail-tcpto - print TCP timeout table
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
successful connections), qmail-remote assumes that further
attempts will fail for at least another hour.
qmail-tcpto prints qmail-remote's current list of timeouts.
qmail-tcpto must be run either as root or with user id
qmailr and group id qmail.
