[Cecil Westerhof]

A bit strange: I did not see messages for a few days and now I get a lot.

​No the only server line is:
    server   = news.eternal-september.org

​I do not think that this is the problem, because when I give:
    ​telnet news.eternal-september.org nntp
I get:
    Trying 213.239.209.88...
    Connected to news.eternal-september.org.
    Escape character is '^]'.
    200 news.eternal-september.org InterNetNews NNRP server INN 2.7.0

Easiest to put a FQDN on the "server = ..." line.

​news.eternal-september.org is a FQDN.
