[TriLUG] simple mail filter. best option?

[Cristobal Palmer]

I have a site, bar.com, that will be receiving mail from clients such
as foo and baz who have their own domains, foo.com and baz.com.

I want to set things up such that mail to foo at bar.com only gets
through if it came from *@foo.com, likewise mail to baz at bar.com should
be dropped if it didn't come from *@baz.com.

What's the _best_ way to do this if I'm using postfix? Something
directly in postfix? Procmail?

TIA,
CMP
