msmtp and gpg encryption issues

[Aric Gregson]

Hello,

I have no issues using msmtp to send my mail from multiple accounts with
Gnus (Ma Gnus v0.8). The passwords to access imap accounts are stored in
a gpg protected file that Gnus opens at the beginning of each session
and then stores the password until I quit. I have recently wanted to do
the same for sending via msmtp, but it will not work. I get as far as it
asking for my gpg password and then it fails with error 78. 

I am using the setup from <http://www.emacswiki.org/emacs/GnusMSMTP>,
created a separate file with just the password and encrypted it with
gpg, I then use:

     passwordeval gpg2 --quiet --batch --no-tty -d ~/.test.gpg

which is when it fails. Has anyone else had success doing this? 

Thanks, Aric
