Email server behind pfSense

nahid

One more question how can choose localhost as the interface in Postfix? Appending a line in main config file or some thing else.

The second task that I am going to perform is that I will make a port forward on 25 from my external mail server ip to localhost. But question is my internal mail server ip is 10.10.1.5 and how will I connect this with external mail server. I mean how will the email traffic will receive and send between them?

nahid

Or is it the thing that my local mail server ip is the localhost in postfix forward? Is that so then in domain tab which server ip I am going to provide: local or external email server ip.

Please consider me as a beginner thats why I am asking so many questions.

@nahid:

Another question,

Under Serach email tab in Postfix forwarder Sqlite files are empty. Is my configuration is wrong or I have made something error.

set log Destination to /var/log/maillog and Update Sqlite to every minute on general tab.

Marcelo,

Please look at the screen shots of my Postfix Forwarder. I have done what you say about the sqlite but still it is empty.

Thanks a lot for your reply.

94.55.x.x will be an virtual ip on your pfsense?

if so,
just change 94.55.x.x on postfix gui to 10.10.1.5

Internet –--> 94.55.x.x pfsense--->10.10.1.5 internal mail server

You will have sqlite databases when you have mail traffic on logs

Marcelo,

I have changed following way:

wanrules.png_thumb

NATrules.png_thumb

marcelloc

On port forward, create a nat rule from virtual ip 94.55.x.x to 127.0.0.1

The port forward will create the rule you need on wan interface

O postfix config, choose loopback and lan interface.

nahid

Dear Marcello,

Do I have to disable those port forward on 25 from ExternalMailServer to InternalMailServer or they will be there as like as they are?

@nahid:

yes, all external traffic must go to postfix (rdr from virtual ip to 127.0.0.1 with associated rule applied)

nahid

Hurrah!!!

Marcelo,

I can send emails but can't receive. Is there anything wrong?

If you have enabled the postscreen, the first communication for each ip will be rejected. Just like the spamd feature

nahid

Marcelo,

so what you recommend? If I disable the postscreen I will receive emails. Or there is any other solution.

nahid

That means 2nd time sender will work properly. Am I right?

Yes, try some sends to your domain.
I use postscreen on my setups.
