All the emails are delivered sucessfully from our exchange except to one domain, all emails to this domain is stuck in the que and say "Message routed and Queued for Remote Delivery". And this perticular domain recieve emails from all except our domain. Some days this situtation changes to reverse that, we can send emails but we can not receive. Total three company ( Ourself, email provider, ISP ) is looking to solve this issue but can not. Can any body suggest a solution for this.
