Dear All,
We have a ERP system which use to send email notification to users,using the exchange 2010 SMTP address,now we have migrated to exchange 2013,and i have changed the SMTP address to the new exchange 2013 after ,it seems not to be working,to troubleshoot the issue i tried doing a telnet the telnet is working but the ERP administrator says that the telnet with auth login should work,i found out when i do telnet and do auth login it does not seems to be working,what could be the issue.please see the screenshot below.
