Outgoing? Sieve is currently only applicable to incoming e-mail. If you
managed to do something like this, I'd be interested to find out how. :)

This should solve the first two:

require "fileinto";
require "relational";

if address :is :domain "To" "dept.example.com" {
    fileinto "Dept";
}

if allof (
  address :value "ne" :domain "To" "dept.example.com",
  anyof (
    address :matches :domain "To" "*.example.com",
    address :is :domain "To" "example.com")) {
    fileinto "Company";
}

Unfortunately, I cannot find a way to do #3. Perhaps some extremely
convolved regular expression, but I wouldn't want to go there. Basically
one needs to test that at least one of the addresses in the message does
not match *.example.com, but I don't see how that could be achieved.
