I've got the following problem and looking to find a work around.
My ISP is pretty lame and don't run their own DNS servers. They have assigned me a fixed IP address but can't create obviously a PRT reserve DNS entry for me. Im running I-MSCP and my mail server is being reject by many hosts due to not having a reverse dns lookup entry. Is there any workaround for this as my ISP told me it will take a long time for them to setup their DNS own server.
