smtp setup

Our SMTP needs to do this:

Forward mail for our domains:

 * Accept wildcard mail for a given list of domains, e.g. *@nix.is or specific addresses, e.g. [email protected]
 * Once mail is accepted forward it to another address on a foreign SMTP, e.g. "[email protected]". It should not munge the To: header, just contact bar.com's SMTP and supply "rcpt to: <[email protected]>" in the SMTP dialog

In addition it should:

 * Forward mail for local users (avar/hinrik etc.) to a given E-Mail address, this could be done via ~/.forward probably

And it would be sweet to:

 * Setup mailmain on the machine to have mailing lists
