Cannot receive posts to pgsql-hackers through news server

Hello,

I'm reading the posts of pgsql-hackers through the news server
news.postgresql.org using Windows Mail on Windows Vista, to avoid receiving
many emails. I don't seem to be able to receive posts in June. All I could
download are before June. But I could receive messages in June of other MLs
such as pgsql-general, pgsql-jdbc etc.

What could be wrong?

Regards
MauMau
