No longer receiving messages from this list

[Rolf Ackermann]

Hi all

Before you cry: I have already sending an email to the administrator of 
this list, but no answer!!!

Can anybody tell me why I'm no longer receiving any message from this 
list? I've got message
over 2 years but before two month I'm no more receiving messages. After 
that I've subscribed
once again and got messages for about 2 weeks. But after then no more 
messages are coming.
I've checked everything (firewall, virus scanner, email) but there's no 
blocked messages or
intrusions.

Can anybody help me?

Kind regards

Rolf (aka Spieler67)
