    Hello,

    How would I make it so that Exim only accepts mail from mailservers which have a rDNS?

    Thanks!
    Mini

    Go on, have a guess
    Add the following into the ACL section using the exim configuration editor in WHM:

    Code:
      require verify = reverse_host_lookup
             message = Your mail server IP address ($sender_host_address) has no reverse DNS PTR
    
    You will likely lose legitimate email, though, as there are plenty of SMTP servers that don't have an rDNS PTR record for their IP.

    You should read the Exim manual before making post
