Hi all, I changed Location to my server, (same server, same internal ip, new location, new static ip). I changed all old ip adresses (DNS Manager) to the new static ip adress. Web sites works fine, but I email users cannot connect to their mailboxes from the network (It refuses to connect) I CAN connect from the internal network (eg. it works if i initiate a new (or reconnect to an old) user). From another internal ip emails work fine, I can receive emails and see the old ones ... Any ideas, how to investigate / solve this problem ? Thanks in advance... /P.
