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.
