When I initially installed my server, (about 2 weeks ago) I was receiving emails that I forwarded from my external account. I no longer receive anything that either goes there, or gets generated there.
I wonder if the anti-spam is doing something to prevent it from coming in.
I read the Wiki about whitelisting, and configured the server accordingly, but I still do not receive any email from that account.

Is there a way to check what has been blacklisted? and if so, remove it from the blacklist?
