Hi Gordon,

Sure you can receive email. We worked quite a bit in the email system to
provide the needs for our partners and communities in the field, be it
in Amazon rainforest or Central Africa. I'm happy Winlink has all these
human involvement and provides all these services over HF, and more
importantly, keep it working!

Btw, I never proposed a replacement to Winlink. I'm just commenting on
UUCP over HF, including its uses in remote and war-torn areas, or just
as backup communication. In terms of networking technology, it fits the
purpose very well, while being well supported in any Linux distribution
and email stacks (Postfix, Exim, sendmail). For eg., UUCP is ready to be
installed / used from the app repository (including Debian / Raspberry
OS), while being in use for 40+ years.

Cheers,
Rafael
