Other people on your ISP are spamming. The only things you can do about that are talk to your hosting provider about their reputation and either find a different one or use a mail relay provider such as Mandrill or Sendgrid.

I would recommend talking to them first and then voting with your wallet, even if you decide to use a mail relay provider. Let them know that tolerating spammers will lose them customers.

Judging by the anti-spam talk about this hosting provider, ENZU just love hosting spam. Ditch them and let them know why. It will be years before their reputation improves, even after they start trying to clean up their act.
