      My suggestion is that you don't use an MTA on pfSense at all under any circumstances :-)

      If you want e-mail notifications, there are some PHP modules out there which can just send mail only, not receive.

        Cool, can you point me to such PHP modules I can install in 1.2.3-RELEASE?Ā  I would be more than happy to install them as I don't need the potential security risks of a full-blown MTA on my firewall.Ā  Essentially, I just need to be able to send email from the monit application installed on my firewall(s) to receive alerts, etc.

          I don't know if there is a full-blown sendmail work-alike done in PHP, but someone could use the smtp.inc file from pfSense 2.0 and write a small front-end to it that takes the message and sends it where it needs to go:

          http://redmine.pfsense.org/repositories/entry/pfsense/etc/inc/smtp.inc

          The whole notification system had a lot of work done in 2.0

          You see how the SMTP settings are done here:

          http://redmine.pfsense.org/repositories/entry/pfsense/usr/local/www/system_advanced_notifications.php

          Not sure how much of that would work on 1.2.3 since it only has PHP 4.x and pfSense 2.0 is on PHP 5.x

          You may just have to google around for a PHP sendmail drop-in or work-alike and see what turns up.

              • What does, "ps aux" give you?

              ps aux does not show anything relaled to postfix…

              • How are you trying to start postfix?

              I made the following from the beginning

              1.- pkg_add -r postfix.tbz from (ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-7-stable/Latest/postfix.tbz)
              2.- edited /usr/local/etc/rc.d/postfix, just to change :${postfix_enable="YES"}
              3.- cp /usr/local/etc/rc.d/postfix /usr/local/etc/rc.d/postfix.sh
              4.- Added postfix_enable="YES" into /boot/loader.conf
              5.- Reboot

              • What does your postfix main.cf file have?

              I“ve got 2, but i didn“t changed anything yet in those files

              /usr/local/etc/postfix/main.cf
              /usr/local/etc/libexec/postfix/main.cf

              • How are you trying to connect using telnet?Ā  From the local machine or from a machine on your LAN?

              From both (obviously using localhost from pfsense, and LAN interface ip from LAN)

              Thanks a lot!!!

                  ok. News.

                  I installed a fresh postfix on pfSense Box for FreeBSD 7.2 (postfix-current-2.6.20090212,4.tbz)

                  PostFix is running now (at least 25 port is opened), and ps -aux shows 2 processes running for postfix (pickup and qmgr) but now I got the following message in system log:

                  postfix/smtpd: fatal open database /etc/aliases.db: No such file or directory

                  if I search for aliases i found

                  /etc/aliasesĀ  Ā  (which is a link to mail/aliases) (/etc/mail/ is empty)
                  /usr/local/etc/postfix/dist/aliases
                  /usr/local/etc/postfix/aliases

                  Thanks

                    Great, you are almost there!

                    To get the /etc/aliases.db file created, edit the /etc/aliases file and make any necessary changes.Ā  For me, I changed the "root:Ā  you"Ā  to "root:Ā  rkelley@abcxyz.com" then ran /usr/local/bin/newaliases to build the /etc/aliases.db file.

                    Also, getting the /usr/local/postfix/main.cf file tuned properly is very important!Ā  Here is what I have in mine:

                    
                    undisclosed_recipients_header = To:rkelley@abcxyz.com
                    queue_directory = /var/spool/postfix
                    command_directory = /usr/local/sbin
                    daemon_directory = /usr/local/libexec/postfix
                    data_directory = /var/db/postfix
                    mail_owner = postfix
                    myorigin = <domain_name>unknown_local_recipient_reject_code = 550
                    mynetworks_style = host
                    relayhost = <pfsense_lan_ip>debug_peer_level = 2
                    debugger_command =
                    Ā  Ā  Ā  Ā   PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
                    Ā  Ā  Ā  Ā   ddd $daemon_directory/$process_name $process_id & sleep 5
                    sendmail_path = /usr/local/sbin/sendmail
                    newaliases_path = /usr/local/bin/newaliases
                    mailq_path = /usr/local/bin/mailq
                    setgid_group = maildrop
                    html_directory = no
                    manpage_directory = /usr/local/man
                    sample_directory = /usr/local/etc/postfix
                    readme_directory = no</pfsense_lan_ip></domain_name> 
                    

                    Make sure to put in the correct information for your relayhost, undisclosed_recipients_header, and myorigin.Ā  Once done, simply restart postfix and send yourself an email.

                    Let me know how you make out…

                        Ok. Finished.

                        My pfSense box is able to relay mail to another relay host. After a bit tailoring of main.cf

                        mynetworks_style=subnet
                        relaydomains = xyz.com
                        relayhost = ip.add.re.ss of LAN

                        Apart of your suggestions relayhost, undisclosed_recipients_header, and myorigin

                        Thank you very much for you help

                          No problem, glad to help.

                          Now that you have installed Postfix , please make sure to lock down your firewall as much as possible…
