How-to Allow domains through Anti-Spam in Exchange 2007?

I have some list servs that need to come through our Exchange 2007 server, but I'm not 100% sure how to do it.

On the Anti-Spam tab in EMC, the only thing you can add is the IP address, but I need to make sure the domain is allowed to come through because of things like lists changing thier IPs or maybe they use multiple IPs to send from.

I found this page: http://technet.microsoft.com/en-us/library/aa995952(EXCHG.80).aspx and used "Set-ContentFilterConfig -BypassedSenderDomains *.example.com"  in EMS, but I'm not sure if this is correct.  I also find it hard to believe this can't be accomplished from the EMC.

This is the only Exchange box we have, the Hub Transport and all that other good stuff runs on here.  I am also not on SP1 yet as I haven't had time to install and be around to recover if it breaks.

Any help will be much appreciated.
Thanks!

Hi,
The link that you have got is perfect.
See as far as tasks not possible in EMC and only in EMS....well you are right. See anything that is done on EMC actually run the same cmdlets in the background (ie EMS cmdlets).
MS has not added all functionality into EMC yet, so most of the tasks in Exchange 2007 are done via EMS (ie Powershell)
Hope this helps
Thanks

OK Just so I understand...
The cmdlet I ran: "Set-ContentFilterConfig -BypassedSenderDomains *.example.com" ,with the domains I need replacing the example.com, will work fine?  I actually had a few domains and according to the document above, I seperated them with commas. ex: "...domain1.com, domain2.com, domain3.com".

The only thing I didn't do was put the * in front of the domains, seems I missed that part.  Will that have a big effect?  If so, how do I go back and fix that?

Thanks.

Hi,
The option is
set-contentfilterconfig -bypassedsenderdomain $Null
Also look at this LInk for good reading: http://www.petri.co.il/using-exchange-2007-management-shell-configure-content-filtering-part2.htm
Thanks

OK Cool.
I check the status using: "$list = (Get-ContentFilterConfig).BypassedSenderDomains" and the domains showed up, but the Subdomains showed up as false.

Then I ran your command with the $Null and they were cleared out.

Then re-ran the "Set-ContentFilterConfig -BypassedSenderDomains *.example.com, *example2.com, *.example3.com" and made sure I included the * and this time when I ran the $list, it showed the subdomains as true.

Thanks!

This doesn't look like it's working.  Is there a service I have to restart?

I think I spoke too soon.  I signed up again for the lists I was supposed to be a member of, and the confirmation emails came through.
Looks OK so far.
