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:

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
