Hello, I wrote this few months ago: https://inverse.ca/sogo/lists/arc/users/2012-10/msg00218.html
Accounts management works fine. Other modules are not implemented for now. I'm interested to keep this project alive, but if nobody uses it it will surely die.
It clearly lacks of documentation. If you want to test it, just tell me and I'll write it.
Tell me if you're interested to test/contribute/... Source code is still here: https://github.com/rledisez/SOGoAccountsManager -- Romain LE DISEZ -- users@sogo.nu https://inverse.ca/sogo/lists
