I recently locked down our Exchange Server a bit using the methods outlined in Microsoft's "How to block open SMTP relaying and clean up Exchange Server SMTP queues in Windows Small Business Server" (we use Standard Edition, but the Exchange methods are the same). Although this solved our problems and cleaned a lot up, I still see about 8 SMTP Connector's in the Queue which are obviously spam related.
For example, the listing will show
MYEMAILSERVER - casinosite.com (SMTP Connector) SMTP Default SMTP Virtual Server
I've frozen the obvious connectors, but they still show an unsent email in all of 'em. I've checked our connectors and found that our one connector is configured properly.
How do I get rid of these open spam connectors? Shouldn't the queue just show our one default connector instead of a connector for every domain an email is sent to?
