I experienced a similar problem (not adding postfix to the SASL group) when installing Postfix 2.1.5 using Debian Sarge. I did not have the same problem with Postfix 2.2.10 and Dapper, so I believe that at least that part of this bug has been resolved.
I still had to manually unchroot. -- postfix-tls: Ask if SASL access should be enabled. https://launchpad.net/bugs/8529 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
