[ubuntu-uk] OT - secure email?

Sadly, even MyKolab isn't really secure [0]

Realistically, what are you looking for? It's like the famous "Easy,
cheap or secure, pick 2" statement...

If it's protecting the messages you have sent from inspection (casual
or otherwise on the server), use something like GPG/PGP. Consider
backing MailPile [1] which is a mail client which bakes GPG into the
UI, it's not an after thought. Bear in mind however, that GPG doesn't
protect the metadata of your e-mail, so all the headers are still
there. You may be able to circumvent that by going via Tor, but

If it's protecting the messages in-transit between your client and
your server (in case of someone running a packet capture between you
and your mail server), ensure they're running TLS encrypted SMTP and
TLS encrypted IMAP.

If you want to completely harden your mails, look at BitMessage [2],
which as a benefit, doesn't require a "mail server", as your client is
a P2P node, in a very similar way to how bitcoin works. Bear in mind
though, it's a very new technology, has a small number of users, has
limited client support (nothing on Android/iOS etc), and hasn't even
had a security audit yet.

Out of interest though, please let us know how you get on, and where
you decided to go next.
