Hi I have windows 2003 AD domain with single exchange 2003 server organization I m using smarthost to deliver all external mails via default smtp virtual server. one week back, i installed new exchange serverin myexisting organization and host two new mailboxes on that server. Now when i send mail from new mailbox to existing mailbox or to internet, are delivered sucessfully, but unable to receive mails neither from existing mailbox nor from internet. When i checked message tracking log on old server, it shows mail is quaed for remote delivery and NDR is generated after some time on old mailbox. I m wondering why local mails are getting qaued for remote delivary as both the mailboxes are from same organization and in same routing group. If any one has any solution pls reply.
