And again "The error was: Unknown alias" on incoming emails

Question

Good day for all
I have read all topics about this error, search Google, this forums.
My environment:
Windows 2008 STD SP2 ENG
MOSS 2007 SP2 + April 09 CU ENG
Exchange 2007 + all recent rollup
AD Windows 2003 Native
Exchange, MOSS and DC is a dedicated servers for each.
For this moment, I have use only mail-enabled lists, and all was working excelent. But now I need use mail-enabled groups (distribution groups). First that I did, is enable mail for Owners group of some test site.
Group is created in OU, and all members is in place. I have try add and delete users from that group in MOSS - all changes replicated to AD's group.
Then I try to send mail to that group, in MOSS log I found this errors:
08/02/2009 22:49:12.22  OWSTIMER.EXE (0x0BA0)                    0x02F0 Windows SharePoint Services    E-Mail                         6873 Warning  An error occurred while processing the incoming e-mail file c:\inetpub\mailroot\drop\ec9ec1a901ca13a100000001.eml. The error was: Unknown alias.. 
08/02/2009 22:49:12.22  OWSTIMER.EXE (0x0BA0)                    0x02F0 Windows SharePoint Services    E-Mail                         6871 Information The Incoming E-Mail service has completed a batch.  The elapsed time was 00:00:00.0029298.  The service processed 1 message(s) in total.  Errors occurred processing 1 message(s): Message ID: [email protected]   The following aliases were unknown: owners 
When I execute command stsadm -o refreshdms -url http://sps-lab/sites/test I have another error:
Error in the application.
Same error and for -o refreshsitedms command. 
Account for WSS Timer service and for Central Administration Application pool account is the same. This account member of Administrators group in a MOSS Server and has full control on OU.
I was try setup 3 diffrent servers with MOSS - no luck, same error on each.
Additional information:
Using Reflector, i'm disasemble the refreshdms command. Then I run method's code in my custom application, i've got error Access Denied.
Code:
static void Main(string[] args)
//using (SPSite site = new SPSite())
Uri requestUri = new Uri("http://sps-lab/sites/test");
SPWebApplication application = SPWebApplication.Lookup(requestUri);
if (application == null)
throw new FileNotFoundException(SPResource.GetString("WebApplicationLookupFailed", new object[] { requestUri.OriginalString }));
foreach (SPSite site in application.Sites)
site.RefreshEmailEnabledObjects();//Error is here
return;
Error:
{"Server was unable to process request. ---> Access is denied.\n"}
Inner StackTrace:
   at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)
   at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
   at Microsoft.SharePoint.DirectorySoap.SPDirectoryManagementProxy.ModifyDistributionGroup(String Alias, String Name, String Description, String ContactCN, RequestInfo Info, DistributionGroupFlags Flags)
   at Microsoft.SharePoint.SPGroup.ChangeDMS(String dlAlias, String newFriendlyName, String newDescription, String requestor, Int32& jobId)
That can i do more for troubleshooting?

Hi,
You mentioned that Central Administration Application pool account is a member of Administrators group in a MOSS Server and has full control on OU, but I am not sure how is the content application pool configured.
If the content application pool account was not the same with Central Administration Application pool account, please make sure:
Grant content application pool account with Design permission to Distribution Groups list in Central Administration > Operations > Approve/reject distribution groups.
Follow the step by step guidance to configure the incoming mail:
Configure incoming e-mail settings (Office SharePoint Server) (http://technet.microsoft.com/en-us/library/cc262947.aspx)
After successful configured the DMS enabled incoming mail, you should see a request record when assigned a email address to a SharePoint group in Approve/reject distribution groups page and the group would be created automatically if the request was approved.
Hope the information can be helpful.
