Re: Password sending mail only once

[Richard Riley]

The basics of the password caching are bits with "cache" in them below -
as with all systems (well, Linux ones..) the devil is in the details of
how they deal with things like gpg-agent. Unfortunately Linux distros
tend to do things differently but the "same" kind of ... I battled like
hell with gpg-agent because of the way apps pick up how to talk to
it. 

Bottom line : you need a caching agent. Google up "password cache
agent" with your distro name and throw in emacs too and ...

The mml2015 stuff really confused me a while back because documentation
was thin on the ground and I really didnt know whether to use epa or
whatever. It was kind of in a transition phase at the time.

I suspect if you post your emacs version someone out there will have a
set up for you.
