Hello.Some years ago I missed a function on Courier bofh file. It was to reject connections based on the reverse dns host name.
I made a patch and I use it for arround 4 years with no problems. I use mostly to block direct delivery from adsl/dial-up connections.
The bofh lines look like this: badhost adsl.giga.net.tw badhost broadband.ntl.com badhost cable.primacom.net badhost dial-in.ttnet.net.tr badhost dial-up.arnes.si badhost dyn.user.ono.com badhost dsl.amrltx.swbell.net And courier will block with messages like this: 517 Host rejected: 217.217.64.81.dyn.user.ono.comBlocking hostnames and not IP networks is much more easy to mantain. I hope this helps anyone who missed that feature too.
