        Did you tried stopping postfix process and removing current /var/db file to start a new one?

              I need to configure PostFix to accept mail from a specific IP address even though that address is both blacklisted and is presenting a non-existent host name during HELO.

              I have tried placing entries like this:
              123.231.132.213 OK
              in the "helo" section of the "Access Lists" tab, and also added them to /usr/local/etc/postfix/helo_check
              but I am still getting the following reject message in the logs:
              RCPT from unknown[123.231.132.213]: 550 5.7.1 Client host rejected: cannot find your hostname, [123.231.132.213]

              Could anyone advise me on the correct way to configure PostFix so that it will bypass the helo and RBL checks for specific IP addresses?

              Thanks.

                Hi guys! Sorry for my bad English. I found an interesting bug. The package is sensitive to the hostname. If you do not correct the host name does not occur the record in db file. Example: mail1.example.com working, mail-1.example.com not working. All the matter in the function function_grep_log in file /usr/local/www/postfix.php . Please note this bug in the next update. Thank you.  :)

                  Hi All,

                  Im new in this forum. Im just installing pfSense with Postfix and Mailscanner package as SMTP relay for our Exchange 2003 server.
                  It work very well. Postscreen and RBL checks are the day saver.  :)

                  One thing i want to ask, is it possible to block certain email  address from my trusted (mynetworks) SMTP client ?

                  I had put the email address in the Access List –> Sender, but it doestnt have any effect. I think it is because the order in the **_smtpd_client_restrictions_** and _**smtpd_recipient_restrictions**_ started by **_permit_mynetworks_** and followed by other rules. So if the first rule is passed, it wont check the following rules.
                  Also im trying to change the order from the shell, but when im reload the Postfix from the GUI the main.cf back to default order.

                  smtpd_recipient_restrictions = permit_mynetworks,
                  reject_unauth_destination,
                  reject_unauth_pipelining,
                  check_client_access pcre:/usr/local/etc/postfix/cal_pcre,
                  check_client_access cidr:/usr/local/etc/postfix/cal_cidr,
                  check_sender_access hash:/usr/local/etc/postfix/sender_access,
                  reject_non_fqdn_helo_hostname,
                  reject_unknown_recipient_domain,
                  reject_non_fqdn_recipient,
                  reject_multi_recipient_bounce,
                  reject_unverified_recipient,
                  reject_spf_invalid_sender,
                  permit

                  Thank you

                    Hi expert_az,

                    I think you have configured the Postfix to listen on multiple interfaces.
                    You can workaround this issue by listening postfix on localhost only and then nat external ips to 127.0.0.1. (http://forum.pfsense.org/index.php/topic,46334.msg242753.html#msg242753)

                          Hi all,

                          I seem to having a little issue with the widget for this package.

                          Emails are flowing in and out fine but the widget does not show the number of emials which have been rejected etc.

                          The only disply the widget shows is the number of "Sent" emails which are emails that have passed through successfully and allowed into my exchange server.

                          I am not using the additional mailscanner and I am running pfsense 2.0.3 i386 and postfix forwarder 2.10.0 pkg v.2.3.5

                          Any ideas or tweaks I need to make?

                          Thanks and cheers all.

                            Hi jemarti, try to put it in the Access List –> MyNetworks.

                              Jemarti,

                              you can add that IP to mynetworks but it would be far better to email the owner of 123.231.132.213 and ask him to fix his DNS entries so that IP address resolves to the host name sent in the HELO/EHLO command.

                                Hi

                                My postfix db /var/db/postfix takes a huge space. I would like to purge postfix sqlite files.
                                Can I just remove old files ?

                                  sqlite3 database_name "VACUUM;"

                                    I don't know the database_name…
                                    FYI, the folder contents many files [date].db

                                    Also, as I understand, this command will reclaim space in the database This will not remove data.
                                    I want to delete old entries.
                                    As it is split in multiple files, would it be possible to keep some of the latest .db files and delete the oldest ones ?

                                        This might be off topic but I'm using this package to relay mail into and then outside of my network both using ipv4 and ipv6. I was wondering if there would be a way to change the webgui config's logic so that if you do not select an interface to listen to it would essentially populate the master.cf using one smtp service entry in the master.cf

                                        ie:
                                        smtp      inet  n      -      n      -      1      postscreen

                                        I think technically using postscreen for inbound traffic & relaying outbound is not the correct method to implement but with my tiny MX environment I feel it's not an issue.

                                        My setup also has the custom main.cf rules form filled in with the following also…

                                        relayhost = [smtp.somewhere.net]
                                        inet_protocols = all
                                        inet_interfaces = 127.0.0.1, [::1], 192.168.1.254, [fd00:470:bce0:1::254]
                                        smtp_bind_address = 0.0.0.0
                                        smtp_bind_address6 = fd00:470:bce0:1::254

                                        Every time I update to a recent snapshot it seems that I've had to resave all settings in the webgui, then hand tune the master.cf,  copy it and the rest of the /usr/local/etc/postfix/* configs over to the /usr/pbi/postfix-i386/etc/postfix dir. I essentially came to all of these a good while back when I moved from the stable release to a snapshot build and discovered everything was horridly broke…. :-)

                                        My question now is basically, are there any plans to make this a bit more ipv6 friendly? and could I get some thoughts on the postscreen for in/out relaying as well? Perhaps there is some future changes that will ease my frustrations and/or I'm all for even assisting in the creation any changes.

                                        Cheers,
                                        Brian

                                          Hello Marcelloc, nice to see you again in another thread :-)

                                          i have a little question about the postfix forwarder package, i'm getting the errro:

                                          postfix/postfix-script[21723]: fatal: the Postfix mail system is not running

                                          And another one: the file /usr/local/etc/rc.d/postfix.sh isn't executable, is this correct?

                                          Best regards from Salzburg
