Our club has had Mailman Discussion lists on Dreamhost since 2007. Within the past 2-3 weeks error messages like the following are arriving almost every day. I myself am now blocked from the lists I run. Here are samples of what I'm finding in my inbox...

Is someone on diego.dreamhost.com spamming??? And is anyone else having this problem out there?
I opened a ticket with support, it went unanswered for 5 days. Hope somebody can help because I don't really want to move them.
