Hello,
I saw it, I do not want is to have to do this!
What version of pfsense and postfix stable so I do not have to do what Marcello recommend?
Grateful.

azekiel

2.1

but you can savely do that.

The only workaround I found for this is

install package from pfsense gui

go to console, remove pbi packages(not the gui)

Install postfix package via pkg ng

The main postfix binary works fine but all other sub process it starts die with missing libs.

I don't know if writing a guide to use pkg ng will help or add a lot of extra problems.

The main problem with this(and many others) package is that pbi messes up bin and lib location. I have the gui fixed for sqlite2 /sqlite3 but for now, just removing pbi and installing postfix pkg will keep postfix working on 2.2
If I push the gui fix for 2.2 on github, it will broke package gui on 2.1

first of all, great work =)

so… 2.1 is old/out of production already, right?

pfsense 2.1, yes but the package is working on both(2.1 normal install and on 2.2 with the fix above).

Marcelloc, why not to make on the contrary - on pfsense 2.2 normal install, and on pfsense 2.1 with the fix?
It will move more people to update to version 2.2

@marcelloc:

To get postfix working on pfSense 2.2, follow these steps:

Remember, do it at your own risk ;)


fetch -o /usr/local/www/postfix.php http://e-sac.siteseguro.ws/px22/postfix.txt
fetch -o /usr/local/www/widgets/widgets/postfix.widget.php http://e-sac.siteseguro.ws/px22/postfix.widget.txt
pbi_delete postfix-2.11.3_2-amd64
rm -f /usr/pbi/bin/libexec/postfix
rm -f /usr/local/etc/postfix
rm -f /var/spool/postfix
rm -f /var/mail/postfix
rm -f /var/db/postfix
pkg install postfix

I tried the above in 2.2.4 but I had no luck. Can anybody confirm this is working in the latest version of pfSense?

marcelloc

Yes, it's working for sure.

Do not forget to install the package via gui before the steps above…

Hello,I follow step to remove old postfix.

fetch -o /usr/local/www/postfix.php http://e-sac.siteseguro.ws/px22/postfix.txt
fetch -o /usr/local/www/widgets/widgets/postfix.widget.php http://e-sac.siteseguro.ws/px22/postfix.widget.txt
pbi_delete postfix-2.11.3_2-amd64
rm -f /usr/pbi/bin/libexec/postfix
rm -f /usr/local/etc/postfix
rm -f /var/spool/postfix
rm -f /var/mail/postfix
rm -f /var/db/postfix
pkg install postfix

And reinstall postfix and postfix forwarder.
The same settings but it's will show relay access denied when mail incoming.
How to fix it?

akong

Sorry,
I have fix it.It's installed postfix forward and download two file and replace it.It's all ok.

foetus

Tried the steps.

installed package by gui.
removed folders and pbi as posted by marcelloc.
installed package from console pkg.

Saved every config page to avoid errors.
starting service fails :

Aug 19 11:10:35 php-fpm[24346]: /pkg_edit.php: The command '/usr/pbi/postfix-amd64/sbin/postmap /usr/pbi/postfix-amd64/etc/postfix/sender_access' returned exit code '127', the output was '/usr/pbi/postfix-amd64/sbin/postmap: not found'

What am I missing? Tried this on 2 systems, it looks like I really am missing a step here.

Reposting update guide for pfsense 2.2.x only:

Install package via gui
execute code below via console/ssh

fetch -o /usr/local/www/postfix.php http://e-sac.siteseguro.ws/px22/postfix.txt
fetch -o /usr/local/www/widgets/widgets/postfix.widget.php http://e-sac.siteseguro.ws/px22/postfix.widget.txt
pbi_delete postfix-2.11.3_2-amd64
rm -rf /usr/pbi/bin/libexec/postfix
rm -rf /usr/local/etc/postfix
rm -rf /var/spool/postfix
rm -rf /var/mail/postfix
rm -rf /var/db/postfix
pkg install postfix libspf2

Marcel,

Since the changes required to be compatible with 2.2 for non-trivial packages break compatibility with previous releases, kindly consider creating a new entry in the list of available packages for the postifx 2.2 + versions, then add a note to the 2.1- package to switch to the new one when upgrading.

Of course, as always, easier to ask than to do. Thanks for your efforts!

marcelloc

it will on Pfsense 2.3 when pbi will not be used to package binaries.

For purpose of testing, i have installed the package on a dédicated Pfsense (this mean : not my firewall). This package seems to be a geat job.
Today my "production" smtp relays are manuelly maintened. I decided to test this package.
First surprise is main.cf generated par the GUI.

# Allow connections from specified local clients and strong check everybody else.
smtpd_client_restrictions = permit_mynetworks,
				reject_unauth_destination,
				check_client_access pcre:/usr/pbi/postfix-amd64/etc/postfix/cal_pcre,
				check_client_access cidr:/usr/pbi/postfix-amd64/etc/postfix/cal_cidr,
				reject_unknown_client_hostname,
				reject_unauth_pipelining,
				reject_multi_recipient_bounce,
				permit

smtpd_recipient_restrictions = permit_mynetworks,
				reject_unauth_destination,
				reject_unauth_pipelining,
				check_client_access pcre:/usr/pbi/postfix-amd64/etc/postfix/cal_pcre,
				check_client_access cidr:/usr/pbi/postfix-amd64/etc/postfix/cal_cidr,
				check_sender_access hash:/usr/pbi/postfix-amd64/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

Two times "smtpd_recipient_restrictions".
I also notice in the GUI, there is no way for a flat list for clients restriction.
And sender access list is use with smtpd_sender_restrictions.

At this time (others smtp Postfix relay), i manage 3 differents flat lists for :
smtpd_client_restrictions
smtpd_hello_restrictions
smtpd_sender_restrictions

There is also specifics lists for cidr and PCRE.

Pfsense 2.1.5 and last version of package. Something wrong with my setup.

So i'm a little bit confused the way main.cf is generated from the GUI. Even if I know Postfix can use each list in many restrictions.

Are you sure, the post shows smtpd__clientrestrictions and smtpdrecipient__restrictions

@ccnet:

Better using on 2.2 with manual fixes above.

Can you explain it better? You mean you know a better config setup to implement on this package?

Having an issue.

Since I cannot seem to install the LDAP plugin in any way or form (or even find it somewhere..) I can not get a link to Exchange to import a list of valid e-mail accounts.
Is there a way to edit Postfix (used in combination with mailscanner) to allow all e-mail accounts from a domain?

This is not used as an internal relay, just external anti-spam checking.

yes, I know this lowers the security quit a bit. But having everything blocked now with the same recipient error is the other side of the coin.

I really would just like to the the LDAP connection working. But installing the pkg like by the manual gives an error it cannot be found. And I cannot seem to source it anywhere else.
Did anyone manage to install it somehow?

2.1.5 x64 setup.

Did you tried```
pkg add p5-perl-ldap

foetus

pkg_add pR5-perl-ldap
pkg_add: can't stat package file "pR5-perl-ldap"

that or cannot find package.

Tried your private hosted version from 2012. gives more errors then someone dyslexic quoting Nietzsche.
