I am having a difficulty using this box as a mail relay because it is trying to resolve the clients ip address and can't cause it can't reach the internal dns server for reverse look ups. the client app is timing out waiting for the server to give it a response. is there any way to disable the reverse lookups for telnet so that I can simply use ip address restrictions to allow relaying? or do I need to set up a zone record for each of the possible ip blocks (with generic names) in external bsd servers dns record? I'm still a little new at unix/freebsd so any help you can offer would be greatly appreciated. Thanks, Shane ps already disabled name resolution in sendmail.
