PostfixAdmin 2.2.0 was released on April 29th.
Created attachment 154097 [details] postfixadmin 2.2.0 ebuild Includes fix for #223387 Numerous changes from 2.1.0 including URL and file locations / names. MySQL files are gone in favour of self-updating. Also, the license appears to have changed - The LICENSE file now indicates postfixadmin is GPL-2

Just noticed there's a minor error - on line 64, "DEBIAN/" should be "debian/" - I won't bother uploading a corrected version as this doesn't affect functionality in any way.
Thanks for the updated ebuild. In CVS.
