I understand. The account in question is my personal account, and I'm sure it's not being filtered on my email client. In fact, in testing, I shut down all of my email clients, and used a simple IMAP web-client to check to see if the message was there, pre-filtered so to speak. It wasn't, so I don't think it's making it to a point that I can retrieve it with a client, i.e. probably a Cyrus issue.
