[gentoo-user] Encrypted cell 2 gentoo

[James]

Hello,

I've been googling for some guides on setting up encrypted mail
on a gentoo system and specifically how you would set up the apple
or android phone on the other end. Lots to read. Guidance on the
applications (both cell phone and the gentoo workstations. I guess
that inter-operability is what I'm most curious about. I'm not running a 
MTA, but I could if that helps?
