[SOLVED]Install a Relay Mail Host on pfSense (postfix)

jimp

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? 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. 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.

Sorry for my arrogant attitude…........:(

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

Thanks

rkelleyrtp

Great, you are almost there!

To get the /etc/aliases.db file created, edit the /etc/aliases file and make any necessary changes. For me, I changed the "root: you" to "root: 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! 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 =
         PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
         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. Once done, simply restart postfix and send yourself an email.

Let me know how you make out…

Ok. Good News again.

Now I´ve got prompt from the mail server

I made the following

cp /usr/local/etc/postfix/aliases /etc/aliases.db

newaliases

postfix reload

I will keep you informed

dpcma

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

rkelleyrtp

No problem, glad to help.

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

dpcma

Sure! hehe My pfsense cluster is now a Swiss Army Knife hehe

Thanks again!
