After a bit of reflection and research, my goal is to 
setup a mail server to get started. 

I feel that email are underused and abused on the internet
and all these different communication protocoles aren't
really adding much more. I am thinking, what would it look like
if I was to setup an email server, only for local email, but 
that can be access from anywhere in the world. 

Email are easy to setup on phone and computer with a 
lot of easy to setup clients. (k9, mutt, thunderbird...)

My goals: 

 - Email server with smtp and imap
 - Local emails only
 - Reaching email locally trough mutt
 - PGP or similar
 - Mailling list(?)

What I would like to acheive is an email server only
for local email, but accesible from anywhere. With
this in mind, I would avoid the spam issue that I've
run so many time trying to setup email servers. It 
also feels a lot more secure to have email only within
the server, nothing going in or out. 

With that in mind, lucid.observer could become a hub for
a small group of people to do fairly private communication, 
since email aren't going out to the world. My goal is not
to be 100% anonymous, but with a certain ammount of 
privacy. If email are never leaving a server, it seems
quite solid for a setup. Group email or mailling list
could be added after that too to make it even more 
social. 

Postfix is intalled by default on NetBSD and it seems
like Dovecot seems to be the way to go with IMAP. 

After a few hardware problem, the server is back to life
although still behind the firewall here. 

(this gopher is hosted locally but on a different raspi
so that I can experiment freely with the main lucid.observer
server.)
