I'm not aware of anyone doing server-side filtering, but the thought
had occurred to me several weeks ago. But I have yet to think through the
economic and social impacts of this method. Seems like it would be good for
"the commons" not to send stuff people don't want to read, but I wonder what
it would add to the server load.
Anyway, if you do or can receive mail on a Unix host, your best
bet is procmail. Your filter criteria can get as complex as you can keep
track of in your head while writing the filter rules, and do a lot of
other stuff with it as well. If you go this route, you should drop the
digest version in favor of the regular version. You can search the
subject lines and/or the body of the message.
I don't do any subject/content filtering yet, because I'm
too lazy to decide what I do and don't want to read, and afraid to
miss anything. I mostly use it to sort my incoming mail into
separate folders. Have to. I've already gotten 303 messages today and
there are 2 1/2 hours to go.
As a sysadmin, I couldn't manage without it....
