Hey, that's pretty much what I'm looking for. I know there are plenty out there, pretty much an infinite amount, I've searched google for a bit. I need one that's very simple, that can block addresses as simple as [email protected] or even *@blah.com or [email protected]* for more broad blocking. I want it to also not run any services in the background, and if needed, most likely would run a service when Outlook express starts or is sending/recieving. Or be able to set the service to manual and only have it run when outlook is open and then it automatically ends itself when outlook express closes. Oh and, needs to be able to block AIM IMAP mail too. Like manage to take any mail from blocked senders and autodelete them as fit. I'm just seeing if there's such a thing, because I used to manually put them all in on my two AIM.com emails, but now I'm getting errors when trying to save my settings. So kudos to Aim's lovely online email system.
