Either is completely acceptable so long as you configure the basics (DNS, SPF, DKIM is a good idea… etc). Make sure your software properly responds to 4xx and 5xx errors. Spam filtering rarely considers the e-mail address, except upon repeat messages (keeping track of “reputation” so to say).
Side note: in geekier communities I’ve seen bit-bucket used as well; though the general public is not expected to “get” that reference. All my domains “accept” e-mail at this address (along with all the RFC 821 required addresses).
