So far I've added the gpmail alias in /etc/aliases as a test using the following line: gpmail:|/usr/bin/gpmail I then created the /usr/bin/gpmail script, and ran newaliases. In /usr/bin/gpmail I've got: gpg --encrypt --sign --armor -r hricka...@l33tmyst.com|mail -s Test hricka...@l33tmyst.com When piping stuff to it from the command line it works fine, but when sending a test email to gpm...@l33tmyst.com I get a blank email in response. I think this is because /usr/bin/gpmail is being executed as the 'nobody' user (I setup a whoami script), and I've setup the GPG keys for the 'mail' user. nobody can't use GPG, as it doesn't have a home directory, so is there a way to change the user that Postfix pipes things to with (to mail or any other user with a home directory)? Thanks for all the help. - -- Many thanks Harry Rickards (a.k.a l33tmyst) - -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GAT/GCM/GCS/GCC/GIT/GM d? s: a?
