I use postfix + postgrey. But greylisting doesn't seem to work any more. I detect spam using various scripts. As you put it, "accretion of crud"! I block spammer IP addrs via pf. Probably not the right thing to do. Should look into various anti-spamming mail filters again. It is trivial to manually detect spam so probably should experiment with NN code for this. I too use nmh (and MH before then). But since my last upgrade repl, comp, forw seem to bring up a blank X-MH-Attachment in vi. Used to bring ~/Mail/drafts/ file, initialized with interpreted contents of "components" or "replcomps" file. Haven't gotten around to looking into this. [This is a problem with many "maintained" software packages. Things evolve and if you update only sporadically, you just may miss a crucial update or two!]
