Postfix - antispam and relay package
-
Any ETA on a "Install and Go" fix without needing to manually edit things?
ETA = never. The package is gone from pfSense 2.3.

Mmm… Then I must ask what mail forwarder is pfsense going to replace it with? Surely many people make use of pfsense for dual web and mail filtering and other general firewall purpouses. Scrapping postfix without a replacement would force people to look at other next generation firewalls.

I don't believe any replacement is planned for this. https://redmine.pfsense.org/issues/5374

Does that also mean all the other mail apps like mailscanner, spamassasin, clamav ect will be falling away? Last I checked the Postfix was a MTA that sent all emails to 127.0.0.1 on the pfsense box were they were then scanned and filtered accordingly, PostFix would then send them on there way when they were done. Unless I am understanding wrong, how would I filter my mail now without PostFix?

On your mailserver perhaps? I don't get the idea of running postfix, spam filters and co. on a firewall… Regardless, take this with pfSense developers, I'm not one.

Meant how would I filter my mail without PostFix "On pfSense", but I appreciate your honest replies. What a pity I liked pfSense. Cheers.

I'm migrating the package for 2.3.
If you use pfsense as an UTM, packages postfix, varnish, squid, mailscanner give it layer 7 ability on these protocols.
For me it's really usefull.

Now that is some good news for a change. PostFix "IS" one of the best used packages on pfSense. To scrap it would be going backwards. Happy days :)

Sadly SPF is broken now:
unused parameter: spf_mark_only=yes
This was a very useful option to fight sender address forgery.
Any idea how to fix?

For me, postfix+friends on pfsense a major administrative convenience. And, it is in keeping with the spirit of what is is a 'firewall' does (if only in an expanded sense). Most of the spam traffic won't even succeed in connecting, the ones that do cause internet 'internet spam service check' requests to leave from the firewall without having to take up bandwidth on the lan, and most of the evil attachments never make it past the firewall either. It also (I hope still will) allow one 'clamav' install to manage scanning web traffic for the squid suite and also the mailscanner/email.
Also, having the 'postfix and associated packages" stack in PF allows me to leverage pf's certificate management, destination email domain routing, failover, load balancing for email. That internal domain routing bit is a security plus as traffic for domain X never travels lan segments used by those on domains A, B and C, an obvious security plus. Also it allows the internal smtp world to be very fast and lean as it needs minimal security and no need for the add-on 'nasty-checking' packages.
Remember one of the main spam defences is having the mail exchanger's reverse dns match the common name in the ssl certificate. Anytime information can be kept in one place and closer to where it's used is an admin win.
Last, the postfix config for the lan side can use the lmtp protocol which is a major overhead saver (no per message setups/teardowns).
It calls for a multiprocessor setup, lots of ram and lots of disk. I know that is not exactly what comes to mind using the word 'embedded', but the above is my $0.02 on why it's worth it.
If it were to be removed, I'd have to create not just port forward to a new subnet but a vlan just to isolate incoming email traffic, then – well, it would result in an economic bonanza for the people who sell those coffee thingys.

Sadly SPF is broken now:
Bismarck, have you been able to install from Available Packages? I missed a few days of 2.3 updates but haven't seen the postfix package listed.

Hi biggsy,
the packages should still be there:
http://files.pfsense.org/packages/10/All/postfix-2.11.3_2-amd64.pbi

Hello marcelloc,
since 2.2.x Postfix doesn't write spam logs to the sqlite database, thus you can't search for spam and the widget doesn't display any spam records.
This makes it really hard to track false positives. :'(
Please help!
//edit
when I execute it via putty after I send a spam test, it does write the spam record to the database file!?

Thank you for working on this, Marcello. Is there any news?

FYI
I did a fresh install of pfSense 2.2.6 last week and the Postfix package did work out of the box, expect the search mail & widget sqlite bug, wich can be fixed by fetching the postfix.php/postfix.widget.php from:
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.txtSo NO need to delete Postfix and install it via pkgng!
Regards ;)

yes, I'll need to change the syslog function that enables /var/log/maillog.

It just started up or it's running and filtering email? on 2.2 I got a lot of missing libs erros on postfix subprocesses.

Yes it's filtering email, spam and viruses with MailScanner, I run it as my productive system since 2 weeks now, no lib errors or crashes.
Thank you for your hard work, much appreciated!
