Ispconfig2 : Email users cannot connect after static ip change
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...
