Hosts file & e-mail notification?

[videobruce]

I have a hosts file on my 2k machine. A number of forums that I visit I am not getting e-mail notifications including this one to threads I am subscribed to. I have checked my address and notification options.
Is this the problem?

Possibly, do you have those forum's mail servers in your hosts file?

Nothing I put in there.
This forum works ok. I got this notification.
