Salut,

am un postfix care arata cam asa:

[email protected]:~> postconf -n
alias_maps = hash:/etc/aliases
bounce_size_limit = 1000000
canonical_maps = hash:/etc/postfix/canonical
command_directory = /usr/sbin
config_directory = /etc/postfix
content_filter = smtp:127.0.0.1:10024
daemon_directory = /usr/libexec/postfix
debug_peer_level = 2
default_destination_concurrency_limit = 20
html_directory = no
inet_interfaces = all
local_destination_concurrency_limit = 2
mail_owner = postfix
mail_spool_directory = /var/mail
mailbox_command = /usr/bin/procmail
mailbox_size_limit = 2002400000
mailbox_transport =
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
masquerade_classes = envelope_sender, header_sender, header_recipient,
envelope_recipient
masquerade_exceptions = root
message_size_limit = 102400000
mime_header_checks = regexp:/etc/postfix/mime_header_checks.regexp
mydestination = mail.u.ro, localhost, u.ro
mydomain = u.ro
myhostname = mail.u.ro
mynetworks = 192.168.0.0/24, 192.168.1.0/24, 81.10.11.0/24,
127.0.0.0/8, 213.23.28.85, hash:/etc/postfix/relay-domains
myorigin = mail.u.ro
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.2.8/README_FILES
recipient_bcc_maps = hash:/etc/postfix/recipient_bcc
relay_domains = $mydestination
relayhost =
relocated_maps = hash:/etc/postfix/relocated
sample_directory = /usr/share/doc/postfix-2.2.8/samples
sender_bcc_maps = hash:/etc/postfix/sender_bcc
sender_canonical_maps = hash:/etc/postfix/sender_canonical
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
transport_maps = hash:/etc/postfix/transport
unknown_local_recipient_reject_code = 550

din care stiu, "mynetworks" valideaza permisiuni de a trimite mail
folosind acest postfix. Adesea (de fapt, foarte adesea) gasesc in
coada mesaje trimise de la [email protected] la [email protected]. Detalii:

Received:       from adverto.dk (unknown [125.161.37.223]) by mail.u.ro
(Postfix) with SMTP id 18081488504 for <[email protected]>; Tue, 7 Apr 2009
15:17:52 +0300 (EEST)
To:     <[email protected]>
Subject:        Hey cute
From:   me <[email protected]>
MIME-Version:   1.0
Content-Type:   text/html
Message-Id:     <[email protected]>
Date:   Tue, 7 Apr 2009 15:17:52 +0300 (EEST)

Am setat repede un client de mail pe o statie care se afla in alta
plaza de ip-uri decat cele din "mynetworks", si am testat.

1. Daca pun la recipient de ex: [email protected], primesc un msg de eroare:

The message could not be sent. The authentication setting might not be
correct for your outgoing e-mail [SMTP] server. For help solving this
problem, go to Help, search for "Troubleshoot Windows Mail", and read
the "I'm having problems sending e-mail" section. If you need help
determining the proper server settings, please contact your e-mail
service provider.

The rejected e-mail address was '[email protected]'. Subject 'test',
Account: '81.10.11.8', Server: '81.10.11.8', Protocol: SMTP, Server
Response: '554 <[email protected]>: Relay access denied', Port: 25,
Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79

2. Daca pun la recipent: [email protected], mesajul pleaca, insa este oprit de
spamassassin.

Este clar, ca daca un spammer foloseste serverul meu de mail, poate
trimite spam mbox-urilor din u.ro, lucru care ma deranjeaza, pt ca-mi
ia timpi mari la procesor. Am o scapare, insa nu stiu unde. Orice
sugestie este binevenita. Multumesc!
