Email/Conversations issues?

[Dave]

Since the move my email has been broken, even though it LOOKS like it's set up okay. When researching this, I also noticed that there were some conversations that may or may not have been delivered.

Is anyone having issues with Conversations? Maybe opening one and never getting a response?

I have noticed that when I get an email notification that someone has sent me a pm it gets flagged as spam. It says "nihsen-whatever" is a source of spam.
