Sure, there you go: https://forum.pfsense.org/index.php?topic=43687.msg667576#msg667576

Thanks a lot man!
I appreciate your time

ReisBey

it does not work for me. I have Provet so many times now I have abandoned.

Thansk :(

Bismarck

Sorry ReisBey, sadly there is no easy way to run Postfix on pfSense anymore. :'(

Hi! I don't see any logs too.

"Postfix General Settings > Logging > Destination > /var/log/maillog " enabled.

I create maillog file in Command Prompt (touch /var/log/maillog), and insert " mail.* /var/log/maillog " in syslog file and restart postfix.
But it did not solve my problem

Any ideas?

Sorry my fault, move system.inc from /etc/system.inc to /etc/inc/system.inc and reboot.

@Bismarck:

@Ralph-DE:

I don't see any logs, though. Shouldn't there be a mail log in var/log ?

Did you enabled it in the Postfix General Settings > Logging > Destination > /var/log/maillog ?

And check /etc/syslog.conf there should be a line for it:

…
local7.* %/var/log/dhcpd.log
mail. /var/log/maillog*
.notice;kern.debug;lpr.info;mail.crit;daemon.none;news.err;local0.none;local3.none;local4.none;local7.none;security.;auth.info;authpriv.info;daemon.info %/var/log/system.log
auth.info;authpriv.info |exec /usr/local/sbin/sshlockout_pf 15
*.emerg *
…

Otherwise, everything will be logged in the system.log facility, which can be very noisy. :P

I've tried to play with /etc/syslog.conf to make the mail log working again, but it's seem to be a bad idea.
This file is recreated after reboot and the previously added line disappear.

So I added the line mail. /var/log/maillog* into the /etc/inc/system.inc instead.
I add it after the line local7.* %/var/log/dhcpd.log
then reboot.

Now the file /etc/syslog.conf have the correct line for logging and postfix is logging correctly to the maillog.

Thanks !

Hi everyone!
A special thanks to marcelloc for the work he done. it's awesome.
I try to configure postfix at pfsense 2.3.2 and can't solve the problem with recipients from AD. Filled all the fields at the gui, but nothing done. I try to receive recepients in SSH with the command```
/usr/local/bin/php /usr/local/www/postfix_recipients.php

extracting from 10.168.1.1...error while binding:The wrong password was supplied or the SASL credentials could not be processed
There is no backup file for 10.168.1.1...(0)
Total ldap recipients:0 unique:0

But I'm sure I wrote the password correctly. Can anybody help me with this problem?

In Domain try: dc=testdoamin,dc=ru this is how its working in my setup.

And you could check AD login via Diagnostics > Authentication but you need setup a DC in System > User Manager > Authentication Servers first.

Good luck.

poteh

Thanks for your reply, Bismarck.
Try your advice - the same result. Also try pfsense@testdomain.ru as Username - the same. But if I type CN=pfsense;DC=TESTDOMAIN,DC=RU in Username filed then I got an error:


extracting from 10.168.1.1...Use of uninitialized value $passwd in string eq at /usr/local/lib/perl5/site_perl/Net/LDAP.pm line 427, <data>line 755.
error while binding:The server requires the client which had attempted to bind anonymously or
without supplying credentials to provide some form of credentials

P@ssw0rd: not found</data>

But I'm not sure that ; is right here.
Used Diagnostics > Authentication- everything allright. Moreover, I use AD authentication to the gui.

Hello team, I need help with the pfsense postfix forwader antispam tool postscreen.
I have to disable those after greeting Tests - greylisting Problem with Office365 Mails:
postscreen_bare_newline_enable no
postscreen_non_smtp_command_enable no
postscreen_pipelining_enable no
How can I manage this ?
Kind Regards,
Hanno

For permanent changes you can edit file: postfix.inc

there you have the file with changes I made for my config;
It include a warning notice for the lines you want to disable, that settings will delay receiving emails but you can disable from antispam config, no need to delete it.

Solved my problem. Our AD wanted username in user@domain.ru format. So I edited /usr/local/bin/adexport.pl file


:51#our $bind    = $ARGV[2].','.$ARGV[1];  # AD account 
our $bind    = $ARGV[2];

and filled the domain field as DC=TESTDOMAIN,DC=RU, username field as pfsense@testdomain.ru and that works.

After upgrade to pfSense 2.3.3 Postfix does not start any more. The error message is "shared library libicuuc.so.57 not found".
Any help?

Which version of Postfix do you run? It looks like you need to update the postfix/icu pkg.

How many people does still need antispam and dkim outgoing mail signing feature running on pfSense?

I know Netgate does not want or need it as a package on current pfSense versions but I'm updating postfix package to 2.3.x as a manual procedure in the user at your own risk way.

How many people does still need this running on pfSense?

I know netgate does not want or need it as a package on current versions(I've asked a lot of times), but I can try to update it to 2.3.x or 2.4 as a manual procedure in the user at your own risk state.

I will say this is a must if you want to be sure that at least pfsense notification will be emailed to you.
If wan ( or lan ) go down and you don't use this package, you will lose all notification and is a good chance that logs will be overwritten until connection is fixed.
And in my case I am using it also as a backup (mx2) for primary mail server (mx1) that is on another location…

Install process and search mail tab is almost done. Will take a look on widgets, view config and queue tab.

The process will be simple as execute a script on console/ssh. ;)
