One of our mail servers was blocked for being a spam host. No actual spam was sent. No the whole problem was the mail server said it's host name was localhost. This was a simple oversight in the sendmail config, not actual spamming of any sort. Yet, without warning, those self righteous fuck heads blocked the server.
Had they sent a warning, I would have quietly and meekly fixed the issue, and I would have appreciated them pointing out the issue. But thier shoot first and ask questions policy is just fucking asinine.
Should any private organization be allowed to fuck with anyone elses traffic? No. But these zero grit dildo think it's there position in life to do just that.
