Hello,

I'm using a adsl connection to the internet and use fetchmail to get
my mail. I'm also running portsentry to log security violations.

In the Netherlands the adsl connection is provided by MxStream where
originally the adsl-modem uses PPTP. A few days ago I "tweaked" the
modem from the "home-version" to the "pro-version" and now I don't
have to use PPTP anymore but the connections run via PPP and the
modem is used as a router. The connection whith the provider is now
done by the modem and not by software (PPTP).

Everything is running great but since that time, every moment when
fetchmail gets my mail, I get tons of messages in /var/log/messages
as shown below.

Does ayone knows what is going on, and how to get rid of these
messages?

Regards,

Marco
