问题
I currently have this code in my htaccess file stored in the root:
RewriteEngine On
DirectoryIndex index.php
RewriteCond %{HTTP_HOST} admin.mydom.com$
RewriteRule ^(.*)$ /admin/system/$1 [L]
RewriteCond %{HTTP_HOST} ^([^/.]+)\.mydom\.com$
RewriteRule ^(.+)$ /subdomains/%1/ [L]
RewriteCond %{HTTP_HOST} !mydom.com$ [NC]
RewriteRule ^(.*)$ http://www.mydom.com/$1 [L,R=301]
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
The file should ensure the following is done on the site:
admin. subdomain is mapped to /admin/system
map all subdomains to /subdomains/{subdomain}
redirect any domain other than mydom.com to mydom.com
and then the standard wordpress htaccess
Its working fine apart from the subdomain part, all subdomains are being redirected back to the main domain (mydom.com)

Have it like this:
DirectoryIndex index.php
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+$ [NC]
RewriteRule ^ http://www.mydom.com%{REQUEST_URI} [L,R=301,NE]
# redirect sub.dom2.com to sub.mydom.com
RewriteCond %{HTTP_HOST} ^(?!www\.)([^.]+)\.(?!mydom\.)[^.]+\. [NC]
RewriteRule ^ http://%1.mydom.com%{REQUEST_URI} [L,NE,R=302]
RewriteCond %{HTTP_HOST} admin\.mydom\.com$ [NC]
RewriteRule !^admin/system/ admin/system%{REQUEST_URI} [L,NC]
RewriteCond %{HTTP_HOST} ^(?!www\.)([^.]+)\.mydom\.com$ [NC]
RewriteRule !^subdomains/ subdomains/%1%{REQUEST_URI} [L,NC]
RewriteRule ^(subdomains/|admin/|index\.php$) - [L,NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]

You can try to change the beginning:
RewriteEngine On
DirectoryIndex index.php
RewriteCond %{HTTP_HOST} admin\.mydom\.com$ [NC]
RewriteRule !^admin/system/ /admin/system%{REQUEST_URI} [L]
RewriteCond %{HTTP_HOST} !^www\.mydom\.com$ [NC]
RewriteCond %{HTTP_HOST} ^([^/.]+)\.mydom\.com$ [NC]
RewriteRule !^subdomains/%1 /subdomains/%1%{REQUEST_URI} [L]
RewriteCond %{HTTP_HOST} !mydom.com$ [NC]
RewriteRule ^(.*)$ http://www.mydom.com/$1 [L,R=301]
it avoids multiple rewrites
But I do not know if it was the source of your problem

You can use the following rules :
RewriteEngine On
DirectoryIndex index.php
RewriteCond %{HTTP_HOST} ^admin\.mydom.com$
RewriteRule ^((?!admin/system).*)$ /admin/system/$1 [L]
RewriteCond %{HTTP_HOST} ^((?!www\.).+)\.mydom\.com$
RewriteRule ^(.+)$ /subdomains/%1/ [L]
RewriteCond %{HTTP_HOST} !mydom.com$ [NC]
RewriteRule ^(.*)$ http://www.mydom.com/$1 [L,R=301]
Clear your browser's cache before testing this.
