exchange 2003 sp2 not sending to outside domains
Posted on 2011-02-14
we have 2 identical exchange 2003 servers. 1 server functions fine. the 2nd server will not send to outside domains. the email sits in the queues and then ends with a ndr. have double checked dns. have checked spf records, have checked ms records. do not know what to check next. i wish to press 2nd server into service once I get it to send to outside email the ndr states: ndr status 4.4.7; message in queue expired. the sending server tried to relay or deliver the message but the action could not be completed before the message expired. the 1st server can send to the same domain, so I know it is working. thanks for the help.
