Sorry, let me rephrase my question:

Problem:
* I have put all user names on my network in the /etc/postfix/alaises file
and the alias name is "all".
* All members inside my network can send mail to allmydomain.com which
is nothing but the "all" alias.
* The problem now is, anybody from outside (internet) can also send mail to
allmydomain.com .
* Obviously this is dangerous.

Requirement:
I need to restrict mails to allmydomain.com from outside (internet).
At the same time, I also want the mails from outside sent to
allmydomain.com to be redirected to a local mailbox ( like
postmastermydomain.com).

Tested and Failed:
Reference: FAQ, topic "Protecting Internal email distribution lists".
I modified /etc/postfix/access to read the following:

/etc/postfix/access:
    all permit_mynetworks,reject

Result:
Mails from outside (internet) to allmydomain.com are still recieved.
Mails from inside are also recieved.

Awaiting your response,

Regards/Thanks

Vasudeva
