Xwall -- Is it Working Right?

[Coldfuzion]

I know that this is not an Xwall forum, but they often take 24 hrs to respond on thiers and xwall is talked about alot in here, so I thought I would ask.
I have had it running now for about a day, it sits on it's on server, takes in email and sends it to my Exchange 5.5 server. I dont have mail going back out through it, i let me exchange server just send it out. Im running a network with about 60 mailboxes.
I got it due to constant spam and even more constant RNDR's (messages from <>). I have gone through all the settings, configs, recommended starting settings, etc... yet i am still seeing email come in to it and bieng allowed to from <> as well as completly bogus domains and email addresses.
I know xwall can block this, but what is the best settings to do this?
Any help or insight would be greatly appreciated.

You need to configure the white list, where Xwall reads the list of valid email addresses on your Exchange server, and only accepts email for these addresses.

Thanks.I'm glad that will kill the <> filling up my q's. One last question, I added to attachment blocking .htm and .html thinking it would just block attachments with those extensions, yet i'm seeing that it blocks any email written with html formatting, not just attachments. Unfortunantly, most using outlook, etc... have this feature on. Any way around this besides allowing those attachmenst?

Thanks.
