Postfix - antispam and relay package
-
For internal clients, the best way is to include their hostnames on your local dns.
Setup your pfSense box to use your internal dns.
But, if you are using dns Forwarder on pfsense, you can also include these host info on it.
And don't forget to save postfix config after any host change.

what a pity to disturb, look I'm working and making changes to the cfg and Services: Postfix relay and spam, but not working.
not to do just what I want is a postfix relay host, that I may have a serviodor forwarder external mail, which is in zimbra
using a generic account with authentication and security is, with STARTTLS
as I have written before I had the problems that no longer do.
thanks
for your collaboration -
mauricioniñoavella,
As we saw in ermal post, package cyrrus has a missing dependencie in pfsense. Its not a missing compile arg, so there is nothing I can do to Fix it.
For now, postfix Forwarder Does not has SASL option.
If you want a quick solution for that, buy some commercial support hours as ask pfsense team to Fix it.
If you google for you problem, you will find that openldap client requires cyrrus too.
good luck on your trouble shooting.

mauricioniñoavella,
you must understand one thing.
pfsense's team released version 2.0 with no need of cyrrus-sasl library, so the problem is not with pfsense's team.
Packages are contributions and almost created and maintained by community, so when a package has a problem, the problem is not on pfsense2.0.
When somebody builds a package, all ports compilation is done by pfsense team BUT it does not means that is fully supported by them.
Pfsense is one thing, packages is another thing completely apart of base project.
if you don't like the way libraries are missing on pfsense, try installing freebsd packages on labs.
I'm not angry about anything in pfsense's project, its perfect to me.

To my pfSense also is an excellent project.
In fact I think it is good to realize this problem, as I have experienced that served to improve your package. And that the community forum to find out.
It is very important to account for other versions as I could incorporate cyrrus-sasl library, I hope you will contribute to have been able to let you know this,
Thank you very much for your input.
To think this forum, to share and we want this project. As is pfSense, and do not take as a destructive criticism but a constructive criticism.
I hope you take it in practice because it is a benefit to all who participated in this forum, showing the possible problems that arise in the project, to improve it.
The Free BSD Project was born to be a complete Unix-like operating system free software, software that respects your freedom. and best of all and for all.I will be working to bring you the package for continuous improvement in your work is excellent, because I think an excellent system, and wait when you merge with relay host including cyrrus-sasl.
thanks

HI all,
I've just released package version 2.2 with:
-
Sqlite database log support
-
Widget for dashboard with mail stats
-
Search email tool for diagnostics
-
checkbox to enable or not smtp_valid_hostname_check
-
few more help info for easier setup
-
-
Awsome news. I hope this corrects my issue. I will post something here in a bit that I have encountered.

OK, so the rejects that I have been getting seems to occure when the remote host excepts e-mail on a different public IP than the one it sends from. I discovered this by talking with some IT people that I have been getting all these legitamite e-mail rejects on the helo host not found. They have something like an ironport or barracuda acting as a mail gateway behind a firewall in bound SMTP on a particular IP and then their mail server has a statis 1-to-1 NAT rule that translates outbound sending of mail on a different IP.
I have not idea how to even resolve this since it tries the verify back to an IP that does not listen or forward mail back to the internal mail server.
Please let me know if this is not a clear enough write up on what I am saying.
Thanks for all you do marcelloc

The helo smtp info can be easily configured by email admins, including Micro$oft. The default option is something internal like hostname.local if you do not use any server for relay to internet.
Unckeck this option and see how postfix deals with your spammers.
On my clients networks, I do only accept mail from server that are not misconfigured.
-
on your check box for helo check. I see it says checked for default. So if I check it, I am assuming it will check helo and if it is unchecked it will not check helo?
Thanks,
-
ahhh, I think your updated package has worked. I am starting to recieve these e-mails now. I just recieved the ones from earlier today.
This makes me feel so much better.
Thanks marcelloc
-
Great news. In few days you will have many logs on Database. Take a look on dashboard postfix widget and on search mail.
-
I am currently looking into it. Great work marcelloc.
-
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
