Hi, one of our customers informed me that some mail he is sending is rejected. The return message is:
your IP XXXXX seems to be dynamic - please use the smarthost of your ISP.
This DA server uses a shared IP address. Anyone can tell me how to fix this issue? I googled it and noticed that outlook/microsoft are active in preventing mail that 'seems to be dynamic'.
