restriction_classes lookup.

Hi all,

i have setup virtual domains.

1. i need to create a all@domain.com for every domain.
so any user sending a mail to all@domain.com should
forward to all users in that domain.

All my virtual domains are looked up from database.


2. i need to Whitelist sender address based on
recipients .

Is it possible to whitelist a sender to a particular
domain or username. without user restriction_classes
parameter.

I was able to do it through
recipient_restriction_classess. but i don't what to
edit the main.cf each every time to create a new class
for new group of whitelisting.


3. i want to restrict certain domains and users to
outside mails. and restriction them with thier
respective domains.


Desperately looking for a solution. Any ideas will
greatly appreciated.


Cheers,
Sunil
