    apperantly this remote server 10.0.0.1 have no hostname

    How can i make the ip address 10.0.0.1 able to connect without the hostname verification? like skip toresolve hostname in exim configuration if it possible

    Hi @iLinux85


    That notice simply means that there is no rDNS present for 10.0.0.1 which technically there shouldn't be because it's a private IP address not a public one. This isn't keeping mail from being received and it's not something that can be disabled through the exim configuration manager.
