I'm trying to configure a mailaccount so that it will only accept mail from one spesific address.

The other mailaccounts on my server are to accept everything they get.

I have to give som commands in the homedirectory to the user.

What I'm actually going to to is to set up this user as a mailinglist with the .forward file in his homedirectory.

When sending mail to this user the mail are forwarded to everybody on the list, but I don't want everybody else to use this address - to prevent spam. So I want to set it up so that only mail from me are forwarded, and everybody elses are denied...

How do I do that?
