advice on buying firewall hardware

Mon 22 October 2018

Several people have asked me recently what hardware I would buy today for use as a home firewall.

for a total of $176, including shipping. Links were accurate as of October 22, 2018.

This gets you a tiny box, similar in size to random commercial house router/firewall/wifi access points, which can run a standard Linux operating system with a complex firewall running at 1 Gb/s in and out, more RAM than strictly necessary, and an SSD which is both very large (and therefore can last a very long time) and boot the system quickly enough that you can do a reboot without losing TCP sessions.

I would also recommend a medium-sized USB thumb drive to set up as an emergency booting and backup device. Call it another $15 or so.

replace procmail with maildrop

a nice improvement in maildrop

Thu 26 July 2018

Way back in 2014, I wrote about my two stage mail filter system. At the time, I had to use a helper program called deliver-to-maildir in order to get my read messages correctly delivered as seen, rather than new.

In the intervening time, Sam Varshavchik, the primary programmer of Courier and maildrop, made some improvements. The really useful one is this:

   if (/^To:.*school@domain.edu/:h)
   to "| /usr/local/bin/deliver-to-maildir seen $HOME/Maildir/.school/"

can now be handled like this:

   if (/^To:.*school@domain.edu/:h)
   to $HOME/Maildir/.school/

Much cleaner, and you can either set FLAGS once at the top of your mailfilter or inside a scope just before your to delivery.
