Postfix - antispam and relay package

marcelloc

I unchecked "Helo Hostname" in antispam page, but it seems that the postfix is still reject the mail from unknown host.
RCPT from unknown[114.251.18.30]: 450 4.7.1 Client host rejected: cannot find your hostname, [114.251.18.30]

The helo check verifies the helo info, the log you sent is the host check. The best way is to ask remote admin to fix his dns or if you trust remote domain insert his dns on pfsense dns overide or include this host on my_network.

Hi Marcello,

In the Postfix Forwarder, I cannot search mail.
I set the logging destination and the sqlite update freq. but in the search mail tab the sqlite files box is empty.
And when starting a search it says 'Please select at least one file' which I am not able to do…
Looks like sqlite is not functioning?

Ideas?
Thanks!

marcelloc

did you included subject log on acls?

what happens when you run postfix updade database script on console?

JesusQ

Hi Marcello,

I reinstalled the package and all is working fine now,

Thanks for your time!

@mauricioniñoavella:

This is for
Forum and BSD developers pfSense
I do not understand why people who work in this great project, such as pfSense, stop the publication of a package, which is not compatible with pfSense.
Please do not degrade this great software such as pfSense without offending anyone, first of all congratulate marcelloc and Postfix antispam and relay package has problems.
But I do recommend working to improve, and we who belong to the family of pfSense, are the ones who try and give them guidelines for improving pfSense.
PfSense do not compare with other systems or software firewalls, for there is but I have reviewed (ClearOs Linux), and has a very simple setup SMTP Relay with Authentication. (relay host)
I hope this is taken into account

excuse me to everyone in the forum especially Marcello Coutinho, so writing here

Postfix relay and 2.0.2

I recently upgraded to 2.0.2 and now postfix will not start, I scanned the forums and this thread for anything similar but I didn't see anything.

After upgrade reboot, postfix didn't even appear, I uninstalled and reinstalled and now it shows up under services but it will not start. When I SSH into the console and try to start it I get:

[2.0.2-RELEASE][peter@]/usr(13): /usr/local/etc/rc.d/mailscanner start
eval: cannot open /var/run/MailScanner.pid: Permission denied
Starting mailscanner.
Can't call method "close" on an undefined value at /usr/local/libexec/MailScanner/mailscanner_create_locks line 69.
Error: Attempt to create locks in /var/spool/MailScanner/incoming/Locks failed!
Can't set GID 125 at /usr/local/sbin/mailscanner line 1541.
/usr/local/etc/rc.d/mailscanner: WARNING: failed to start mailscanner
[2.0.2-RELEASE][peter@]/usr(14):

Any help with this would be appreciated, I love using this to relay my mail.

marcelloc

Mailscanner runs with postfix user, check it user exists on pfsense and then try to reinstall mailscanner.

Dragyn

Sorry I didn't post full info, I am running postfix as well, and the user is there. This all worked fine under 2.0.1 so it has to do with whatever changes came with 2.0.2 to pfSense. I am also getting log entries of:
mailscanner: Cannot write pid file /var/run/MailScanner.pid, Permission denied
in the system log when trying to call mailscanner from the command prompt.

marcelloc

try to create these missing folders and permissions.

Marcelloc,

Thank you so much for taking the time to put this package together and help so many of us. Being new to PFSense, I just want to make sure I configure it properly because this is our only firewall. Here's what I'm a little concerned about:

1. Right now I have a NAT Port Forward configured as:
Interface: WAN
Protocol: TCP
Destination: WAN Address
Destination Port: SMTP
Redirect Target IP: My internal exchange server IP
Redirect Target Port: SMTP
- I read here: http://forum.pfsense.org/index.php/topic,46196.0.html you say "remember to remove nat from port 25 and allow access on wan firewall rules to postfix." So I delete this port forward? If so, can you tell me how to properly configure the rule such as the Interface, Protocol, Source, Destination, etc.?

Thanks again!!

marcelloc

Just take a look on current rule your nat has created and replace internal destination IP to wan address.

Make sure your Postfix is configured and running before using it with real traffic.

Hi,

I have Pfsense version 2.0.1 and I just installed postfix package.
I do that because i need a relay smtp.
I have many temporary users on my network. They all have an Internet access provider different (Orange, Free, etc …).
I can not change the configuration in their smtp mailer.
This is why I would like to add a rule on my router so they can all go through the SMTP server of my ISP.
Can you do it with your package postfix?
Thank you in advance.

@marcelloc:

Hi all,

I've just finished postfix package version 2.3.

Postfix is an amazing mail forwarder that really keep away any misconfigured server or server trying to forge email.
Postfix Forwarder package at pfsense has many antispam features but for now, no SASL support for remote authentication.

Zombie blocker (postscreen)

Header chekcs

Body checks

Access lists

RBL checks

SPF checks

Dashboard widgets with mail stats

Sqlite logs support

Sqlite logs forward to use only one box to search mail

Package permissions to allow users to just search mail or view queue

Search mail tool

view postfix queue in gui

And you can also use an third part antispam engine like mailscanner or policyd v2 for a complete antispam solution.

note: NEVER try to install policydv2 freebsd package, it will break out your pfsense.
if you plan to use policydv2 you must put it on other server or in a jail.

The mailscanner tutorial(or package) is under development, for now you can configure by hand using pkg_add -r MailScanner.

att,
Marcello Coutinho

I think you will need authentication for these clients.

You can manually install and configure sasl as current version does not has this integrations on gui.

Can you tell me if this can forward to a port besides 25? I have pfsense at work, and I run an email server at home, but Comcast just decided to block port 25. Was hoping to configure the mx records to point to my office, and it would forward all mail to my home email server.

It will not filter based ou source ip as all your mail will have your comany address as source.
