No, I am OK with keeping unencrypted local copies, at least on my home
machine.  I only expect "pretty good" privacy over the pipes, not
"protection from an FBI home raid" privacy for local copies of my email.
(I don't use disk encryption but probably should.)

The issue is simply: what's the best way to do this? My setup uses
offlineimap to sync a Gmail account (berkeley.edu's institutional
choice...) to a local Maildir.  Mutt only temporarily decrypts messages
when I read them, unless I manually store an unencrypted copy somewhere.

So to accomplish the suggested setup conveniently with the programs I
currently use, I think I would need to:

1) Tell Mutt to automatically save messages somewhere when I decrypt
them.  (Is there an option for this?  I only see fcc_clear, which is for
outgoing messages.  Should I call decrypt-save from message-hook?)

2) Tell offlineimap *not* to sync the decrypted messages folder back to
Gmail. (Easy enough with offlineimap filters.)

3) Tell notmuch to index the decrypted messages folder.  (Again, should
be easy enough.)

Does that sound reasonable?  Do others have similar setups?

I find it sort of telling that I didn't come across recommendations for
setting things up this way when I was configuring these programs.  I'm a
bit surprised that there doesn't seem to be a "standard" solution for
reading and searching archived mail that arrived encrypted.  (I'm also a
bit dismayed, since part of my concern is to find a solution that
doesn't just work for me, but to which I can point non-technical users
when I ask them to send me encrypted messages.)  It still feels very
much like email encryption is possible for the dedicated, but
inconvenient enough for the average user -- and even for fairly
technical users -- that most will avoid it.

I guess I'll try to write up a blog post about how I solve these
problems, once I get a working configuration.  A more comprehensive
solution will have to await someone more talented than me.
