Postfix - antispam and relay package

marcelloc

I'll include the sasl option in the install. The idea of this package is to give sysadmins an excellent smtp layer 7 filtering /proxy.

Excellent work @Marcelloc, thank you!

The fatal maybe related to a restart call to a process that is not ruining.

Good to see that this package is useful for community.

I just update my install on 2.3.2-p1 with your new script without any problems ( with sasl changes from Bismark ).

Thank you all.

marcelloc

These changes will be merged soon.

There are other improvements that will be merged soon.

Long life for community contributors :D

Noticed 3 little things,

1. postfix_postwhite.template isn't copied to /usr/local/etc/postwhite.conf

		//save file
		$postwhite_domains = preg_replace("/\s+/"," ",$domains);
		include("/usr/local/pkg/postfix_postwhite.template");
		file_put_contents($postwhite_conf , POSTFIX_LOCALBASE . "/etc/postwhite.conf" , LOCK_EX);

2. additional domains don't get added to postwhite.conf, maybe because of 1.

3. postwhite is looking for postwhite.conf in a different place anyway

# Read config file options
if [ -s /etc/postwhite.conf ] ; then
	printf "\nReading options from /etc/postwhite.conf...\n"
	source /etc/postwhite.conf
else
	printf "\nCan't find /etc/postwhite.conf. Exiting.\n\n"
	exit 1
fi

and I had a cronjob for this every morning, cant see where postwhite is executed here?

Thanks. :)

/edit

We need policyd-spf_time_limit = 3600 in main.cf if SPF Lookup is enabled or we get a lot of those lines in maillog:

Great job! Package works fine.
Thank you very much guys!

I found a little mistake.
On "Access Lists" page, when i click on field "Sender" and "MIME" i'm redirected to http://www.postfix.org/pcre_table.5.html page :)

Another bug ??

I found that widget is not displaying correct status.

I have configured postfix as backup relay MX2 on Site2 - it receive external mail from WAN if primary mail server MX1 on Site1 is unreachable and it store and forward all email by VPN Site - to - Site.
I also receive all emails from Site2 - from all LANs - and forward them to primary email server on Site1 by VPN Site - to - Site.

But until it receive a email from WAN ( Update Sqlite was on 1h and now is on 10 min), widget is not display anything for that day; emails from LAN are not showed;
As you can see it is missing day 10 and day 11 was displayed only if I blocked primary mail server to receive emails from WAN and email was delivered to MX2 and then forwarded to MX1…

p.s.
I just found also this one in log probably related to Postwhite:

postfix/postscreen[34560]: error: open /usr/local/etc/postfix/postscreen_spf_whitelist.cidr: No such file or directory

Because you need to run /usr/local/bin/postwhite manually first, can't find any code atm in the package, which would trigger it automatically.

Just running Postfix as a Mail Proxy and my widget stats are very accurate.

no luck:

fixed postwhite config file creation and etc path call

Bismarck

Thanks, the widget shortcuts are handy. :)

Can I run "install_postfix_23.sh" script again or I must remove all installed packages first ::)

@Igor:

As far as I can see, it should not be a issue, just run the script again.

marcelloc

Included postfwd functions to limit messages per user and time based on package.

To use this funcion you must run the install cpan modules script from pkg-mailscanner

https://raw.githubusercontent.com/marcelloc/Unofficial-pfSense-packages/master/pkg-mailscanner/files/install_cpan_modules_23.sh

Fist time implementation, not used to run postfwd, so feedbacks are always welcome.

@Bismarck:

Yes, but it looks like the widget just counts high scored spam and not all, same when searching for spam in postfix_search.php it just finds high scored spam and the numbers of high scored spam are are always the same in the widget and MailMatch.

The point is that database gets the last status from message. 'Normal spam' on your configuration are sent to user, this way, last state is sent, instead of spam.

I've pushed a commit that updates the status only when it's not a spam message
https://github.com/marcelloc/Unofficial-pfSense-packages/commit/d6dcd6d63ae83886aa9da00f545137fa2cd6b046

Also, I've include 7zip, rar and PDFID patch to mailscanner package, just re-run install to get latest updates.

Thanks for Bismarck and danny at tweegy.nl 8)
