but

my mailserever appesars blocks all e-mails received. Below I show part of
the

maillog. Any
idea?

Tutorial

Adding greylisting to your FreeBSD - Postfix
system

BSD Daemon Greylisting is an important tool in the war against spam,
servers

who connect to our mail server for the first time are given a 450
recipent

address rejected error and are sent
away.

A 450 rejection is not a permanent error and an RFC compliant mail server
will

try and resend the email later, but on the other hand the tools spammers
tend

to use do not adhere to standards and will not bother to try and resend
the

message
again.

Reasons why we should care? It saves system resources, since we are
stopping

its delivery in the first place and wont have to filter out so much crap
out

later on, and its very easy to
implement.

So how do we go about implementing this? stick with me and i will run
you

through the process although this article is based around FreeBSD, it is
not

much different to get greylisting working on other systems with minimal
of

changes.

cd /usr/ports/mail/postgrey/ && make install
clean

Edit your /etc/rc/conf file and add the
line:

postgrey_enable =
“YES”

Also edit line 45 of the file /usr/local/etc/rc.d/postgrey.sh and change
from

postgrey_enable=${postgrey_enable:-"NO"}

to

postgrey_enable=${postgrey_enable:-"YES"}

Open the file /usr/local/etc/postfix/main.cf and add the line (all on one
line):

smtpd_recipient_restrictions
=

permit_mynetworks,reject_unauth_destination,check_policy_service

inet:172.0.0.1:10023

Now run the
command:

postfix
check

From the command line to check we dont have any
problems.

Then start postgrey
with:

/usr/local/etc/rc.d/postgrey.sh
start

And restart postfix with the
command:

postfix
reload

Use the
command:

tail -f
/var/log/maillog

To check we dont have any errors showing up in the logs we should also
see

entries similar
to:
