Tens of thousands of our 200,000+ customers are no longer receiving e-mails from our domains. We found that Symantec blacklisted our server’s IP address. They won’t say why or when, but have confirmed that they have removed the entry.
This keeps us from sending to our customers who use MSN, Hotmail, USA.NET, and many other domains. They are not receiving statements, transaction information, receipts, etc.
Symantec is telling us we need to reach the admins at MSN, Hotmail, etc. and have them update their spam filters. As you can imagine, it’s impossible to get responses out of most of these folks. Those that respond are telling us it’s a problem between Symantec and us.
How do we hold Symantec accountable for what amounts to electronic slander/libel? (Please note that we are in charge of our own DNS and mail servers, and have confirmed proper setup of our DNS MX records, etc.)
