NAME
       qmail-tcpto - print TCP timeout table

SYNOPSIS
       qmail-tcpto

DESCRIPTION
       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.
