Hello,
I have written a patchset for RoundCube, to integrate PostfixAdmin's functions: password change, vacation, forwarding - and also to copy user's full name from postfixadmin's db when creating the default identity.
You can get my code here: http://nejc.skoberne.net/rcpfa .
Please send bug reports and feature requests to my e-mail.
Thanks, Nejc
