421 4.2.0 sender rejected AUP#SNDR

Messages are again getting through.  It took a few hours after hanging up with Dan the other day for my messages to start coming though. Started getting messages that were sent within the past 2 days in random order.

Dan referred to the spam filtering company as "Cloudmark". He said he has access to a ticket system to create tickets about issues like this. He said that regular users don't have access to that ticketing system, but I did find this web form where you can submit a request to unblock an email address: https://www.cloudmark.com/en/contact.

Cloudmark responded to Dan's ticket saying that "users" had reported messages coming from my email account as spam, which is obviously bullshit since I only EVER send messages to myself. They lifted the block on the email address, which is why messages started coming through.

The problem is that it could start happening again and there are no magic words I can say to a tech support person that will get me to someone who knows what to do.

I also brought up the issue of randomly delayed messages. Dan said he would create a ticket with cloudmark to address that.
