I accept your point of view Michael, though I am surprised by it. > As a former technician at an ISP i also know that getting RDNS can > sometimes be in fact a problem, especially on newly assigned network > blocks. Yes, it took me over 12mths to get my local ISP (BT) to rDNS my static IP. During that time my IP inherited dynamic red flags from FIVETENSRC and the like for previous spamming episodes that BT had (apparently) allowed. I found it tedious and irritating. I now have the appropriate rDNS allocated to my IP. > <snip> While a valid RDNS is preferred there is nothing wrong > with that. Fully agreed and noted. > Missing RDNS is at best a very weak indication of spam. Fully disagree - two years monitored previously cited. From my point of view, here at my site, every single 'Unknown' connection attempt has *PROVED* to be complete rubbish. The reverse is not logical nor viable. > If you really want to take this into account, use it as part of a > scoring system (e.g. spamassassin) but not as a sole reason. I don't use SA and I hope not to, it uses up too much horse power. I wanted the <nounknown> plugin as a mechanism to reduce CPU load should my scamming/spamming shadows escalate their decade long, round the clock, infernal machinations. > People like you make email less reliable day after day. Yes, it's possible though I don't necessarily agree. It's spam that makes email MUCH less reliable day after day. > If you do > not want to receive mail, just shut down your MTA. I want to receive mail. I don't want to receive spam. Just about all my spam logging lines result from 'unknown' connections. Hence my polite request for assistance with this new plugin. BTW and FWIW the server is my own server. It runs here, just feet away, in my lounge as a SoHo (small office home office). What I allow to connect to my own aegis is surely up to me. Whatever policy is used here is REALLY not going to affect any infinitesimal fraction of the outside world - one iota. I hear your pain but am perturbed by its tone and content. ----best wishes, Robert
