How to allow one emailaddress full access (Postfix 2)
 

I have a mailserver running on a Debian distribution and all is working well. I have configured Postfix to only allow email to and from a couple of domainnames, and reject everything else. How can I allow one single emailaddress (blah@blah.com for ex.) to be able to mail to every possible domainname? I've read about regular expressions but honestly, I am not ready yet for regexp :) , it's quite hard ...

Any help/tips would be greatly appreciated!

No tips regarding this issue? Anybody :) ?

I'll try this one more time :) Could anyone answer my question regarding this issue? I want to allow one single email adres to be able to mail to all domainnames possible, but the rest mustn't be able to. So, johndoe@domain.com would be able to send email to wherever he desires to, yet janedoe@domain.com shouldn't be able to. I already managed to configure Postfix so there are only 3 domains allowed to email through the system. They may send email to the same 3 domains only.

Any tips?
