Postfix help needed

I'm looking for someone with excellent email server and Postfix knowledge to give me some tips and help. I have a small email server running under Debian 9 and Webmin/Virtualmin. It needs a little Postfix setup modification. This is what I want:

Generally I use a SMTP Relay/Smarthost ('relayhost', usually SocketLabs) to send emails via SMTP. But for 2 or 3 email recipients the emails should NOT be sent via the SMTP Relay (not using 'relayhost'), but directly from my email server.

1. Can you set up such a configuration? Maybe using 'transport_maps'?

2. Plus a few Formail (part of Procmail) commands.

My system:

– Debian 9.9

– Postfix, Procmail, etc. (used as mail server)

– Virtualmin/Webmin Pro

A few bidders misunderstood this project and what I want. Therefore here're a few more detailed explanations:

I'm running a small Linux mailserver based on Debian 9, Virtualmin, Postfix, and Procmail. All outgoing emails will be sent via an external SMTP Relay/Smarthost ('relayhost', usually SocketLabs). This configuration already works well without issues. But now I want to change a little bit on the mail flow. The work consists of 2 steps:

Step 1: The outgoing emails for a few recipients, who are included in an "Exceptions" list on the server, should NOT be sent via the SMTP Relay (not using 'relayhost'), but directly from my email server's standard SMTP function. All other outgoing emails should still be sent via the external SMTP Relay. More details please see the uploaded PDF flowchart "[login to view URL]".

Step 2: This relates to the "Procmail" email filter and MDA that is working on this server. For a special email flow I'm using a special Procmail recipe. Into this recipe we need to add a few lines with "Formail" commands to manipulate the mail headers (need to add and remove a few header lines). This 2nd step has nothing to do with the email flow in step 1. I need help writing the correct "Formail" commands for mail header manipulation. Formail is part of the installed Procmail package.
