Exchange 2010 spoofing

Hi Experts

We have a spam issue where we are receiving spoofed emails, to get around this we removed the domain sender permission from the default receive connector.

This stopped the spam issue but unfortunately we do need to also receive ligament emails from another mail server which sends using our domain. To get around this I assumed I would just need to create another receive connector in exchange and white list the IP of the other mail server, this doesn't work though as the default connector just picks up the mail and rejects it before the new connector sees it, is there any way around this?

Someone may proffer an Exchange-centric solution, but you may want to consider a hosted  anti spam solution. A feature of most of these, if not all, is a way to block all spoofing your email addresses.  We use Mimecast and have found it to be a solid system.

thanks for your advice, this is something we may look at in the future but at the moment we don't really have much of a spam problem, just an issue with spoofed email which I'm sure can be resolved within exchange.

If memory serves you need to remove the IP of the other email server from the list of accepted IP's in the default receive connector then create a new receive connector and add the IP into there.

I suspect the default still has the IP of the other serve listed so is picking it up first.
