Yes, on Utilities: List Settings: Email Submitted Content: Security, you'll see an option called "Only Admins Can Send" which defines the list so that only list administrators are allowed to send to it.

Then, to make replies go elsewhere (not to the list), change the reply-to field in Utilities: List Settings: Email Submitted Content: Header Rewrites to be administrator@acme.net. Then, the Reply-To: for mailing list mail will be this administrator address, rather than the mailing list.

Note: You can also change the From of the message, so that the author of the message is also rewritten.
