Apache Redirect subdomain from 2 different ports

Good days people

I’m running a webserver on port 80 and and email server on port 82 on the same server over home ADSL.

I have a primary domain example.com as an A-record with www.example.com as a CNAME to example.com. I have configured apache so that both domains using both ports 80 & 82 to redirect to the mail server.

example.com:80 --> mail server
example.com:82 --> mail server
www.example.com:80 --> mail server
www.example.com:82 --> mail server

This is all “working” as it should and as the way I want it – I think…

Now I have a subdomain exclude.example.com that I struggle with. I’m trying to configure both exclude.example.com to access the web server on both port 80 and 82.

exclude.example.com:80 --> web server
exclude.example.com:82 --> web server

but currently exclude.example.com:82 is still redirecting to the mail server.

Below is my apache config

<VirtualHost *:80>
ServerName example.com
ServerAlias www.example.com
RewriteEngine on
#RewriteCond %{HTTP_HOST} example.com [NC]
RewriteCond %{HTTP_HOST} !exclude.example.com [NC]
RewriteRule ^(.*)$ http://www.example.com:82 [L,R=301]
</VirtualHost>

<VirtualHost *:80>
ServerName exclude.example.com
ServerAlias exclude.example.com
DocumentRoot "${INSTALL_DIR}/www/exclude/"
<Directory "${INSTALL_DIR}/www/exclude/">
Options +Indexes +Includes +FollowSymLinks +MultiViews
AllowOverride All
Require local
Require all granted
</Directory>  
</VirtualHost>

<VirtualHost *:82>
ServerName exclude.example.com
Redirect / https://www.example.com
</VirtualHost>
