I think that it's doubtful that Google performing anti-spam filtration based upon statistics and mail flows could be framed as discrimination or being anti-competitive, but I've been wrong before.
If Jaroslaw Rafa hasn't created their Google Postmaster account [as advised in the article linked to in the error returned by Google when they bounce your message with this error] they should probably do that first. If they already have a Google Postmaster account for their domain - what it says in there would probably be pertinent to discussing their issue here. From my own personal experiences managing mail servers - the few times I've seen a client complain about this kind of issue they did actually send spam - or at least one of their mail accounts on their domain did and they weren't aware of it. I'm not saying that's what has happened, but it was the cause of this issue in every case I've ever had to deal with it for our clients. As we do outbound spam filtration the issue is admittedly rare for us.
