Now i have found the solution. It seems to help to ask you. ;)
The solution was to change from listen = [::] to listen = *, [::]
There is no explanation for it - just try and error ...
This is not dovecot's fault. See here: http://serverfault.com/a/39561
I never write that something is the fault of dovecot. ;-) As i complain the configuration is not so easy as before.
But what is the meaning of the addional "*," now? Listening specially to IPV4 and IPV6?
In short: In Linux, binding to :: means "bind to both ipv6 and ipv4". Setting /proc/sys/net/ipv6/bindv6only to 1 changes this behaviour, and Debian had this by default in some testing versions of squeeze, as was recently discussed on the asterisk-users list: http://lists.digium.com/pipermail/asterisk-users/2013-March/278296.html
Aha - thank you for this hint. I have an additional problem with a R8169 ethernet interface loosing IPV4 communication.
But at this time the binding for IPV4 is not deactivated. root@PC# cat /proc/sys/net/ipv6/bindv6only 0
