enigmail doesn't use gcr under the hood, it uses whatever GPG agent is listening on the socket pointed to by the GPG_AGENT_INFO environment variable. By default, in Ubuntu, it's gnome-keyring-daemon, and not gpg- agent.
If you want documentation besides what is in the dconf schema description, please file a bug here, and attach it to this one: https://bugzilla.gnome.org/enter_bug.cgi?product=gnome-keyring Thanks. ** Package changed: gcr (Ubuntu) => gnome-keyring (Ubuntu) ** Summary changed: - GCR has no man page and employs insecure defauts for GPG passphrase caching + gnome-keyring has an inadequate man page and employs insecure defaults for GPG passphrase caching -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gcr in Ubuntu. https://bugs.launchpad.net/bugs/1325833 Title: gnome-keyring has an inadequate man page and employs insecure defaults for GPG passphrase caching Status in “gnome-keyring” package in Ubuntu: Confirmed Bug description: The GCR package has no man page or other documentation that would explain how the GPG passphrase caching is configured. For a package that deals with a critical piece of security infrastructure that is not acceptable. It defaults to caching GPG passphrases for the whole session which again is not good security practice.
