unsubscribe revisited

I'm as annoyed as the next guy when reading the "please unsubscribe me"
messages in a mailing list.
To my excuse I have to say that I have tried everything, unsubscribe
via mail as instructed in the "Welcome to.." message received when
first subscribing.
This did not work so I tried via the web interface, still no go.
Then I mailed the "pgsql-jdbc-owner", no response.
So now I have no more ideas but writing directly to the list PLEASE
unsubscribe me !!!!

Lars.
