PPTP causes Postfix reload

    Hi folks,
    lately I set up a ubuntu hardy 8.04 server with postfix, clamav, spamassassing with the help of this tutorial (http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu8.04) what I found very useful. As a perfect newbi, i could setup a complete mail server in no time. Thank you Falko.
    Now it comes my question:
    on the same server i also configured a PPTP VPN but every time someone connects to that VPN I get this message in the syslog:

    linux postfix/master[5219]: reload configuration /etc/postfix

    and on the servers screen I can read: reloading postfix configuration .... done.

    I think that there is something conflicting between those programs but i cannot find out where i should look.

    Any help is very welcome
    Franco

    Are there any errors in the mail log?
    What are the outputs of
    Code:
    netstat -tap
    and
    Code:
    ifconfig
    ?

    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:
    Oct  2 08:48:01 linux pppd[17890]: found interface eth0 for proxy arp

    Oh, I can see.
    I thank you for taking your time.
    Next week this server will go live.
    All the tests went without problems so far, so I hope that there will not be bad surprises.
