Well, I'm not really blocking any specific mailservers. In my case, I'm blocking messages that Spamassasin thinks are spam. I am also trying to actively push some of the load of spam back onto the smtp servers that are sending it. My assumption is that a number of these are hijacked windows machines, in which case maybe my filter will slow them down a bit. Others are either open relays (and deserve the extra load), or the direct source of the spam. (There is a possibility that someone is getting caught here that shouldn't be, but there isn't a solution to that until something like the 'senders permitted from' or RMX standards that authenticate From: addresses are deployed.) > > Additionally, I don't think the more complicated solution of using > localmailfilter would solve my problem because then I would never > receive the email, which, thought I don't read, I archive.

I'd like to at least log the sender and receipient of all mail rejected by my .mailfilters/smtpfilter, but it's not clear if this can be done nicely. I also wind up running spamassassin twice.. once to check if the message is spam in .mailfilters/smtpfilter, and the second time to put the headers on it so I have an idea what kind of spamassasin scores mail that *does* get accepted for delivery has. > Morally, I should inform the legitimate email senders that their > message was not received by me.
