Your post arrived at the list
I am having the same problem as you at the moment, I am not receiving any mail
from debian-user (or other debian lists for that matter). You can see your
(and my) posts by going to the debian mail list web site.
I thought I was alone, but the volume of mail on the lists seems down, so I
suspect a few people are having this problem.
First they ignore you, then they laugh at you,
then they fight you, then you win. --Gandhi
