Spamd is a fake sendmail(8)-like daemon which rejects false mail. It is
|
|
designed to be very efficient so that it does not slow down the receiving
|
|
machine.
|
|
|
|
spamd considers sending hosts to be of three types:
|
|
|
|
blacklisted hosts are redirected to spamd and tarpitted i.e. they are
|
|
communicated with very slowly to consume the sender's resources. Mail is
|
|
rejected with either a 450 or 550 error message. A blacklisted host will not
|
|
be allowed to talk to a real mail server.
|
|
|
|
whitelisted hosts do not talk to spamd. Their connections are instead sent to
|
|
a real mail server, such as sendmail(8).
|
|
|
|
greylisted hosts are redirected to spamd, but spamd has not yet decided if
|
|
they are likely spammers. They are given a temporary failure message by spamd
|
|
when they try to deliver mail.
