If the spammer uses the outgoing alias directly, then
it never touches the majordomo program, and the mail program
is just looking at a regular alias.
The step that would be wise is to put some kind of hash key
in the name of eash outgoing alias:
foo: .... majordomo..... foo-outgoing-asfdj23991
foo-outgoing-asfdj23991: Include ....
This asfdj23991 is really security by obscurity. It is not real
security. But since you have to log on to the server to find
the key, 99% of your spammers will not see the key and will not
be able to find it.
