Hi

We just stopped to use a Exchange Smart Host (for Spam Filtering) and I need to setup the Echange to basic setup where no Smart Host is used.

I found refences to Smart Host Server at:

EMC / .. Organisation Configuration / Hub transport  / Send Connectors /  Windows Exchange Internet Send / Network
and
EMC / .. Organisation Configuration / Hub transport  / Send Connectors / Windows SBS InternetSEND SERVERAME / Network

and I removed them from there.

I can' receive emails and if some tries to send emails to that server's email addresses he will get an error message as followes:

"administrator@mydomain.fi
#< #5.4.4 X-Postfix; Host or domain name not found. Name service error for name=mail.mydomain.fi type=AAAA: Host not found> #SMTP#"

Is there any other places where I have to remove any references to Smart Host?

The ISP has changed the MX:s but perhaps there is something elso to be changed By ISP who takes care about DNS..

Thanks in advantage,

Juha

Can't use those because all mails are now routed via external spam filtering Company. Those tests doesn't work well for this setup.

In the SBS 2003 there were one simple wizard (CEICW or somethiong like that). It where handy tool to fix problems. Perhaps at SBS 2011 there are some similiar tools. I don't know.

Anyways this server where migrated from SBS 2003 server and all Smart Host references come via that migration. Never looked closely SBS 2011 Exchange and I have no idea where to find Smart Host refences or smtp connector references which I now need to remove.

Little confused here, you say you removed smarthost?  usually smart host is where you add your spam filtering company for outbound traffic only.  the ISP MX records will point to the Spam filtering company and they forward on to your static IP.

If you're not using any 3rd party your ISP should have an 'A' record pointing to your static IP and an 'MX' record pointing to that 'A' record.

Hi

Sorry that I didn't provide all information. We changed from on spam filter provider to another one. Anyways the problem is solved now. I was cabable to delete alla samrt host references from the server (at Hardware firewall we allow SMTP only form spesified addresses) and after ISP fixed the problem with mx the system where functional again.

Rgs, Juha
