So yes, spam is a big problem. I manage it in a crude but effective way. I
have a milter (mail filter) that I cobbled together that is invoked by sendmail.
I also have a separate "spam" user. What the milter does is to take anything
that it considers to be spam and rewrites the address so that it goes to the
spam user. I have permissions set up so that I can easily check on spam when I
have time. Oh yeah, another of my curmudgeon credentials is that I use nmh for
my MUA (I'm a maintainer).
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/<number> 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!]
