The perceived wisdom is to read it with a newsreader. I use the
commercial "Agent" program by Forte, but you can get by with Outlook
Express (emphasis on the "Express", not just Outlook).
And if you must use Outlook Express, which has been a nuisance for years
because of its many nasty bugs (development is has been discontinued since
Windows Vista in favor of Windows Mail), please follow the instructions at
<

released in 2006, more than 5 years ago (which might cause you to
reconsider).
Forté Agent has not had a stable release since November 2009, too.
By contrast, Mozilla Thunderbird is actively developed, and security fixes
are released according to the Mozilla schedule. Last I checked, Thunderbird
was lacking in its built-in filtering and crosspost-regonizing capabilities,
but there might be extensions to augment it with that by now.
For (Debian) GNU/Linux, KNode, which is provided by a KDE package, suffices
for me.
