Hi,Can you telnet to the server on port 25 from the local LAN - if no the problem can only be on the server (like the firewall on the server).Leif

Hi,Please run Exchange Remote Connectivity Analyzer https://www.testexchangeconnectivity.com/ to do an inbound smtp email test, it will guide you some general steps for troubleshooting the issue.Thanks,Elvis

Please check on Firewall side for Natted IP and see if the ips are pointing to your exchange server's Ip in the internal network. Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Hi, Be glad to hear it’s working now. Regarding the migration issue, we'd recommend that you start up a new thread for it. We generally focus on one topic in one thread because in this way it will be better for other community members to participate in the discussion, and to search/find specific answers more efficiently in the future.
