Point Postfix to a Smart Host for a Specific Domain (Linux)

Configuring postfix to block all emails except the specified email accounts. If you need allow a emailing only from a particular from the postfix email server you can follow the below steps. Use Transport Mapping. Here we can tell the postfix mail server to sent or disregard the emails. For this we need to edit the postfix configuration file.

Problem
When sending mail to a specific domain, tell Postfix to send to a smart host (i.e. gateway or spam filter) rather than directly to the mail server.

1. Plesk 11.x / Linux:: Unable To Generate Web Server Configuration File Jul 18, 2015. On Plesk 11.5.30 I have just patched with SSLfix.sh. When I run an ssl check I get - Certificate name mismatch I am also getting the following message Unable to generate the web server configuration file on the host because of the following errors.
2. Tune Plesk to Meet PCI DSS on Linux. This section describes the steps that you should take if you want to secure your server and achieve compliance with PCI DSS on a Linux server. Installing the latest version of software. Before you begin, it is recommended to update all the software on your server to the latest versions, if it is possible.

tl;dr
Add a line to /etc/postfix/transport:

recipientdomain.com smtp:filter1.recipientdomain.com
Create a postmap file:

Point Postfix to use the created postmap file by adding a line to /etc/postfix/main.cf:

transport_maps = hash:/etc/postfix/transport
Restart postfix:

Solution

Some large organizations often employ mail gateways, such as Proofpoint to filter incoming email for spam. If you are using a large web email provider, such as Hotmail, Yahoo, or Gmail, their mail servers will often be white-listed. But what if you are trying to send an email to a bank from your office's tiny Postfix mail server? In this case, you will need to point your mail server to the bank's mail gateway.

To do this, you need to create (or edit) your mail lookup table to include the bank's domain, and point any email to their mail gateway, rather than directly to the mail server. This is accomplished via a postmap.

First, you need to create an entry in /etc/postfix/transport file. You can use any file of your choosing as long as you point to it, but by convention, the transport file is used. So, open it:

Add a line in the format domain.com smtp:smarthost.fqdn.com:port. Unless you are specifying a port (i.e. 587 for SSL connection), you can omit the :port section.

recipientdomain.com smtp:filter1.recipientdomain.com

Save and exit the transport file (Ctrl-O then Ctrl-X if you are using nano). Then, generate a postmap file from your transport configuration:

And finally, point Postfix to use the previously generated map any time it restarts:

transport_maps = hash:/etc/postfix/transport

Save and exit the main configuration file, and finally, restart Postfix:
