RE: restricting who can be sent to.
Or so I thought..., that did restrict all mail to the internal recipients as well. I need anyone in mydomain.com to be able to email anyone in mydomain.local, but I need users on mydomain.local to only be allowed to email a few people in mydomain.com, and none of the other members of mydoman.local. I think postfix may not be able to accomplish what I desire, if I am wrong please correct me.

restricting who can be sent to.
Hello, I am in the process of setting up an internal mail server (carver-test.mydomain.local) using postfix, dovecot and squirrel mail. I want the users of this system only be able send mail to a few users in mydomain.com I imagine that there is an easy way to map this to a file, but I can't seem to find anything in my searches. Thanks Postconf -n: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no config_directory = /etc/postfix inet_interfaces = all mailbox_size_limit = 0 mydestination = carver-test.mydomain.local, carver-test.mydomain.com, localhost mydomain = mydomain.local myhostname = carver-test.mydomain.com mynetworks = 127.0.0.0/8 [:::127.0.0.0]/104 [::1]/128 myorigin = /etc/mailname readme_directory = no recipient_delimiter = + relay_domains = $mydestination, mydomain.com relayhost = exchange.mydomain.com smtp_generic_maps = hash:/etc/postfix/generic virtual_gid_maps = static:1001 virtual_mailbox_base = /home/vmail/ virtual_mailbox_domains = mydomain.local virtual_mailbox_maps = ldap:/etc/postfix/ldap-users.cf virtual_uid_maps = static:1001 Carver Banks

Here's the general documentation on restricting who can send where: http://www.postfix.org/RESTRICTION_CLASS_README.html I tried the following: smtpd_recipient_restrictions = check_sender_access hash:/etc/postfix/allowed_recipients reject but it seems that allows me to restrict the user who is sending not the destination address, what I am trying to accomplish is to have many users of this system be able to only email a few addresses, not even each other. I understand if that is not possible with postfix, just trying to figure out if that is the case... If this is strictly an internal system, you can use something simpler, such as: smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/allowed_recipients reject where allowed_recipients lists the valid recipients as: us...@example.com OK us...@example.com OK -- Noel Jones

Hello Everyone, I am seeing weird bounces on my postfix server and can't quite figure out why... It looks like it is failing while passing the mail off to a spam appliance, but from the spam appliance side I see no record of the message. Also Any ideas, I have a couple examples below? Example Mail.log entry: Feb 12 06:17:53 mail01 postfix/smtp[24220]: C06165CE92: to=user.n...@domain.com, relay=175.21.0.67[175.21.0.67]:2525, conn_use=18, delay=16, delays=1.4/13/0/1.7, dsn=5.5.0, status=bounced (Protocol error: host 175.21.0.67[175.21.0.67] said: 250 2.0.0 Ok (in reply to DATA command)) Example Delivery Report (what was returned to sender): Reporting-MTA: dns; mail01.domain.com X-Postfix-Queue-ID: 8A4946447 X-Postfix-Sender: rfc822; outside.u...@outsidedomain.com Arrival-Date: Tue, 10 Feb 2009 10:36:37 -0800 (PST) Final-Recipient: rfc822; user.n...@domain.com Original-Recipient: rfc822;user.n...@domain.com Action: failed Status: 5.5.0 Remote-MTA: dns; 175.21.0.67 Diagnostic-Code: smtp; 250 2.0.0 Ok Thanks Carver

Often this is caused by a poor PIPELINING implementation on the receiver. You can disable postfix PIPELINING with smtp_discard_ehlo_keywords or only for that destination using smtp_discard_ehlo_keyword_address_maps http://www.postfix.org/postconf.5.html#smtp_discard_ehlo_keywords The above is really just a guess (although a pretty good one). If it doesn't help or you want to definitely diagnose the problem you'll need to post a packet capture to the list covering a time period when the error occurs. http://www.postfix.org/DEBUG_README.html#sniffer -- Noel Jones
