So you have put the proxy for https://mail.domain.com inside domain.net virtual host. You realize they are different domains right?
You need to set a separate vhost for that subdomain mail.domain.com and put the Proxy there. Or you can set a _default_ vhost as I mentioned before. Default one is the one that is defined first in the list of vhosts no matter if its name starts with 000 or not.

# Catch all VHost, traffic that is NOT going to domain.net
<VirtualHost _default_:443>
    ServerName localhost_name.domain.net

-->ProxyPass / https://192.168.124.3/
-->ProxyPassReverse / https://192.168.124.3/
    <Proxy *>
        Order allow,deny
        Allow from all
    </Proxy>
.# SSL stuff here

    ServerName domain.net

Another solution would be to use mod_rewrite instead and keep the one VHost you have as default one. You might put something like this then:

<VirtualHost *:443>
    DocumentRoot "/srv/www/htdocs"
    ServerName domain.net
    ServerAlias www.domain.net
    
    #ServerAdmin webmaster@xxxxxxxxxxx
    ErrorLog /var/log/apache2/error_log
    TransferLog /var/log/apache2/access_log

# Catch the mail.domain.com traffic and Proxy to 192.168.123.4
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www\.)?mail\.domain\.com [NC]
RewriteRule .* https://192.168.124.3/ [P,L]

    SSLProxyEngine On
    ProxyPass /ifolder https://192.168.123.4/ifolder
    ProxyPassReverse /ifolder https://192.168.123.4/ifolder
    ProxyPass /admin https://192.168.123.4/admin
    ProxyPassReverse /admin https://192.168.123.4/admin
    ProxyPass /nps https://192.168.123.4/nps
    ProxyPassReverse /nps https://192.168.123.4/nps
    <Proxy *>
        Order allow,deny
        Allow from all
    </Proxy>

    #   SSL Engine Switch:
    #   Enable/Disable SSL for this virtual host.
    SSLEngine on
</VirtualHost>
