Not necessarily. Eg as a simple model, assume that you 'send' a message by publishing it to something like a usenet group (and perhaps that group charges you a fraction of a cent for doing so).
There's no denial-of-service for a client that receives a lot of messages, distributed or otherwise, but still outsider don't see who is sending what to whom.
