Hello, Sorry to bring this to the list, as I'm sure that instructions for this are posted *somewhere*, but I can seem to find them. We are running Qmail with tcpserver, and would like to duplicate the sendmail feature of denying connections from mail servers which do not have DNS setup correctly for them. We are not so concerned with how a server IDs itself, (HELO) just as long as forward and reverse DNS for their hostname/IP matches. The last requirement is that we want to deny these connections with an error message. Denying with tcpserver directly just causes the remote host to contact the next highest preference MX server. Can anyone point me in teh direction of some good documentation on this? My inclanation at this point is to run tcpserver with -p and have it call a program that will deny the connection if $TCPREMOTEHOST is not set. Thanks for your time.
