"my root directory" is awfully vague.  Please read the manpage about where 
~/.procmailrc and /etc/procmailrc go.
I don't know how your ISP is setting you up with your own "root".  If it is 
a truely virtualized server (with your own MTA, etc, configuration), then 
/etc/procmailrc is where you can put global recipes.
If it IS NOT a virtualized server, and you really only have one USER 
ACCOUNT on the server, to which all your different domains deliver to, then 
what you're referring to as your root directory is probably what the rest 
of the *nix world called your HOME directory.

I don't follow your issue about security risk - if all the domains are 
being handled by ONE user account already, then all those domains are being 
handled by ONE user account already.  There are many issues with using 
procmail as an MTA, which it is not, but you'll discover those soon enough 
on your own.  Or, you could check the manpage, where it explicitly mentions 
some of them.

Uh, what directory is that?  You seem to be inventing new terms here, and 
they're not helping to get your concept across clearly.

Yea, direct the mail for that domain to a separate USER created to handle 
the mail for that domain.  If you direct ten domains at one user account, 
there is ONE ~/.procmailrc file there, and while you can manage to do a 
number of things in there if the conditions are right, there are a number 
of things you will have issues with.  $DEFAULT is the same for all ten 
domains, because $DEFAULT is user-specific.
If you address multiple adddresses within your domains, and especially if 
you BCC them, or if there are issues with one domain versus another, you're 
going to have problems, as procmail is not an MTA.  Your MTA believes it 
has resolved delivery to a user and has passed the mail to the LDA to 
deposit it into the user mailspool.  Procmail will not consistently be 
provided with the data necessary for it to act sufficiently like an MTA.
If you REALLY want separate .procmailrc configurations, you should ask the 
sysadm for separate user accounts, and then direct the separate domains at 
them.
