Default PPTP causes Postfix reload

Hi Falko,

I thank you very much for taking your time at my issue
As you can see from the messages ouput below, I connected to the server using PPTP VPN from 08.48 to 08.50

At login time the server screen showed these messages:
[329654.615881] padlock: VIA PadLock Hash Engine not detected.
Reloading postfix configuration ... ...done.
and after logout:
Reloading postfix configuration ... ...done.

The syslog also contains a warning about padlock_sha, what I also cannot understand. Could be that this is the source of the other issue ?

Now here are the outputs of the log files

messages ouput:
Code:
