“Error 554 HVU:B1 [1]” from AOL (America Online) [2]
Don't be terribly surprised if email for website that is normally forwarded to AOL (America Online) [3] stops showing up. Especially if you complain about spam. Because spam can come not only directly to your AOL account, but indirectly, through your website's email server. And AOL, responding to your complaint, will block all the servers that were responsible for handing the spam, including your website's email server.
And don't be terribly surprised if your webhosting company can't remedy the situation immediately. Think the wait time for calling technical support at your webhosting company is long? This is AOL—they handle billions of email daily. And probably receive millions of complaints daily.
So if you use AOL, and have email from your website forwarded, before reporting that spam, please think about where it might have come from. You may end up without email at all!
