Mayayana explained on 8/02/2016 :
Thunderbird is standard. I've also seen
people whose opinion I value recommend
something called Mesnews. But I've never
used anything other than OE6, and I don't
want all the fancy colorcoding or other
extra features, so I can't offer an informed
opinion.

I have found MESNews similar to the old OE6 and it seems to work just
fine. :-)
