Postfix - antispam and relay package
-
This is odd. I am getting an error when trying to go to avalible packages. Are you getting this?
-
This is the error I am getting. It was just working???
Unable to communicate with www.pfsense.com. Please verify DNS and interface configuration, and that pfSense has functional Internet connectivity.
-
It was SNORT HTTP inspect causing the issue.
Anyways, I have a question about the logs. I am not seeing anything showing up yet. I followed the instructions, but don't understand the last line that I highlighted below in red.
Choose how often pfSense will transfer log files to Sqlite database.
To use Diagnostics -> Search mail you need to:
Select Loggin Destination to /var/log/maillog
Select update Sqlite frequency
Inlcude /^Subject:/ WARN line in Acl Headers after all your Subject rules.Thanks,
-
Go to acls tab and include the subject line in header option.
-
OK, got it. I am starting to see data coming into the logs.
You have done an excellent job on this package. Thanks for all your hard work.
Thanks,

I posted a question to the pfSense mailing list and was directed to look at the Postfix relay package. I saw a posting asking if SMTP out was an option, but I didn't see a clear answer to this.
Let me explain my issue…
After converting a network of computers to use a fairly popular 3rd party email service (not my decision unfortunately), users are experiencing very odd issues with email (POP and SMTP based). The 3rd party says we should try different ports, increase timeouts, etc… and they sometimes take days to admit they themselves have an issue (after we have jumped through their hoops).
One of the issues is email taking a while to be sent out of the network to the 3rd party SMTP servers… in many cases, items sit in Outlook… with recipients complaining that they received multiple copies of the same email.
My thought was to see if there was an SMTP server that can run on pfSense 2.0? I would like to be able to monitor the queue, etc… My hope is that the client computers would stop failing/timing out/multiple deliveries and that pfSense would just act as the active sender SMTP server... basically to send out emails from the network directly to the recipient's mailserver... But I need to be able to manage and monitor it easily in real-time and after the fact on specific dates/times to see what is happening with a specific email problem.
Any advice or suggestions? Does the replay package allow this? Or is it simply for inbound emails only?
Regards,
Chuck

If you have static ip on your internet connection and if you could include this ip as a Spf record on your internet dns domain, then you could configure your smtp client option to this package.
I suggest you to change pop3 to imap. It's much better.
Smtp auth with SASL is not working on current version because a missing dependencie in cyrrus-SASL package.
-
So basically just install the package, create spf record for the public IP and point the clients to use the internal firewall IP as their SMTP server. That sound right?
-
Yes. That's it.
On package, try this configurarion:
-
listen only in localhost and lan
-
disable postscreen
-
choose basic header verification
-
do not check Helo valid hostname
-
at acls, include your internal network on client access list
-
-
does this package have a option for users to manage there whitelist/blacklist or any other options they need to configure under there own login page?
-
This package act as a relay for internal smtp server. Postfix on pfsense has no client accounts or user page.

Any word on the postfix AV and anti-spam add-on? Your latest release fixed all the issues I was having. Great package. I am excited to see what will come next.
Thanks Again,

Hi all,
Postfix compilation on x64 now includes cyrus-SASL2 and TLS.
who need or want to test it, reinstall or remove/install postfix package.
No changes in gui for this option. Include all your SASL and/or TLS config in custom main.cf options
att,
Marcello CoutinhoHi Marcello and everyone else
can anyone help me out I would like to send mail from internal to exturnal though this fantastic packege but can't get passed "smtpd_recipient_restrictions = reject_unauth_destination" have tried "smtpd_recipient_restrictions = permit_mynetworks reject_unauth_destination" in custom but it will not override the defaults, tried SASL but don't know how to install it on pfsense, have spent a week doing this before postting so sorry if its in a post elswere, any help or point to any posts that could help or how to override the default would be grateful

mince69meat,
I'ts included in upcoming version 2.3. I'm finished coding and now I'm testing before publishing.
The not so good news is that 2.2 sqlite database is not compatible with 2.3.

to patch 2.2 to accept mynetworks,BACKUP /usr/local/pkg/postfix.inc to /root dir and then edit /usr/local/pkg/postfix.inc to modify postfix declaration.
Do not backup postfix.inc file on same dir, it will break your boot.
look for 'postscreen_access_list=' and include permit_mynetworks:
postscreen_access_list = permit_mynetworks,\n\t\t\tcidr:/usr/local/etc/postfix/cal_cidr\n"look for 'smtpd_recipient_restrictions=' (02 times in file) and include permit_mynetworks
smtpd_recipient_restrictions = permit_mynetworks,reject_unauth_destination,save file, Go to custom options in gui, declare 'mynetworks' list save config and check main.cf file in view configuration tab
Examples: mynetworks = 127.0.0.0/8 168.100.189.0/28 mynetworks = !192.168.0.1, 192.168.0.0/28 mynetworks = 127.0.0.0/8 168.100.189.0/28 [::1]/128 [2001:240:587::]/64 "mynetworks_style = host" "mynetworks_style = subnet" "mynetworks_style = class"reference: http://www.postfix.org/postconf.5.html

Hi marcelloc, knew to edit postfix.inc (would have missed postscreen_access_list, thanks), did not want to edit this file as I'm worried about braking the package on updates, can you comfirm this will not brake anything on update? was looking for a way to override just by the "custom main.cf options" to keep the package as you made it :-) and not cause problems on upgrades as I have boken things in the past by doing things my way and not the matainers way lol
some info for you, installing postfix on x64 I see that cyrus-sasl-2.1.25_1.tbz is installed as dependencie but on a x86 system it is not installed, don't know if you know that, also for the rest of the community pkg_add will not install it properly on x86 :-(
nice work and brill post about adding mynetworks, should help more on here out than just me
respect

The postfix in 32 bit version is not compilled every day just like 64bits. This may be something related to 2.1 working. The cyrrus-SASL has a missing dependencie that was not fixed yet, So you can only use unauth outgoing smtp for now.
About the postfix.inc, if you do the way I described, it will not broke any package update. Just insert the update on file and do not remove anything.
Package update will update postfix.inc
Do it with caution.
I'll send a line to core team asking 32bits updates.
Postix is on 2.8.7 on 64 bits and 2.8.5 on 32.
