Hi,
We use Exchange Server 2010 standard version. We have one mailbox and one hubcas server.
We frequently have email queue issue from the gateway to hubcas server. The mails used to get held in gateway and not reaching hubcas server. Journaling is enabled for all the messages in each database properties.
Jornaling is done to a mailbox in a database.
Below are the events:
A message with the Internal Message ID 14077388 was rejected by the remote server. This message will be deferred and retried because it was marked for retry if rejected. Other messages may also have encountered this error.
