Re: Procmail setup question

I once had an issue with trying to download / filter emails on the
client side that some attachments and the sheer volume of spam was SO
high, that my email client was spending an hour or more just
downloading emails to trash 90% of them.

At that juncture, I wrote a PHP script on my web server (hosted in the
same place) so that I was using their Gigabit switches (or whatever
was between the boxes in their racks) to manipulate the Inbox with
IMAP, rather than downloading it through the Internet.

I don't know if this suits your needs, or if you can get a web server
from the same company that would provide "LAN" access, but if you can,
my IMAP hack looked a lot like this:
http://l-i-e.com/imap/index.phps

I've been using this same code for nearly a decade now, adding more
and more boxes and filters and spam detection for the ones that get
through the ISP spam detector, then through squirrel mail detector.  I
manage to knock it down to a manageable dozen or so spams per day.

At the last point when I could measure the spam / real ratio, I was
getting about 10K spam per day, and maybe 100 "real" emails, and that
was a decade ago when my mail client was downloading them all...  I
daresay that ratio as gone "up" quit a bit since then, but I don't
want to know how high :-)
