Postfix - antispam and relay package

marcelloc

Hi everybody.

It's finally done 8)

Here are install instructions for UNOFFICIAL postfix package for pfSense(R) software 2.3.x

Under console/ssh, fetch the install script, check what it does if you want and then execute it.


cd /root
fetch https://raw.githubusercontent.com/marcelloc/Unofficial-pfSense-packages/master/pkg-postfix/files/install_postfix_23.sh
sh ./install_postfix_23.sh

Once it finishes, all must be in place. If you do not see the menu after it finishes, try to install any pfSense package from GUI, like cron for example.

WARNING

Use it at your own risk.

This script install packages from freebsd and change your config file.

Thank you looks very good so far, just one thing, the Widget always shows reject = 0.

I've updated some improvements on log to database function and search as well. Try updating the gui files or running the install process again.

Also check if you have reject logs on /var/log/maillog.

Hello marcelloc, I did run the install process again but no luck, reject is still 0 and I have different stats about the spam count in MailWatch as well.

Any idea?

BTW SPF and DKIM integration is awesome, thank you!

marcelloc

Do you have any non word character on server name like antispam-01 ?

The stats on widget are based on destination recipients. Is this what mailwatch does?

A message sid can have more then one destination recipient.

The spam message on widget is specific for spamassassin message that has the alert on logs with 'is spam'.

@marcelloc:

No its just pfsense

The stats on widget are based on destination recipients. Is this what mailwatch does?

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 spam message on widget is specific for spamassassin message that has the alert on logs with 'is spam'.

Yes, but for some odd reason, only the high scored spam gets logged to sqlite.

In the first unofficial version, the logging to sqlite was working fine, nothing changed since with my setup, except the new Postfix package.

If you like I can send you my maillog?

/edit

Searching for spam in postfix_search.php before the update in a sqlite db it shows all spam messages, the low and high scored.

Send me the link on private message.

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.

There was some logic error on widget I've fixed too.

There was also an index on database that suposed to be unique but wasn't. Fixed this too.

Thanks for your feedback. :)

ps: Your mailscanner and spamassassin looks working really great. Did you had to change a lot of default gui config or rules? Are you using other spamassassin rules?

I've applied the patch and it looks very good so far! :)

I've changed a lot of small things and yes I use custom scripts, rule channels and clamav sigs etc. but I think a good bayes training is the key.

If you like a can pack it all together for you?

Muito obrigado novamente! ;)

@Bismarck:

Sure. Is it something I can apply on mailscanner package installation?

Sure why not. I'll make you a list of the things and files and where to get them.

Hello marcelloc,

thank you for your work and this package… Is there any documentation on how to enable postfix as smarthost and to relay via gmail smtp?

I'm trying to configure it as the old package (in pfsense 2.2x) that was working as smarthost for the internal lan, with relay via my gmail account: the only instruction I've found are http://ghanima.net/doku.php?id=wiki:pfsense:postfixmailrelay but I can't make it work (different paths) and various errors in /var/log/system.log

@pf-disa - you could try (untested but would make sense)

cd /root

fetch https://raw.githubusercontent.com/marcelloc/Unofficial-pfSense-packages/master/pkg-postfix/files/install_postfix_23.sh

nano install_postfix_23.sh

go down to line 81 and edit like this:

Install postfix package

pkg install postfix**-sasl** libspf2 opendkim libmilter py27-postfix-policyd-spf-python p5-perl-ldap

and then

sh ./install_postfix_23.sh

to get rid of the compatibility warning add

smtputf8_enable=yes
compatibility_level=2

to the custom main.cf options

@marcelloc

This package is getting in a really beautiful shape, its so sad that its not be in the official repo. :'(

Anyway excellent work! :)

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!

marcelloc

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.

n3by

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
