We have recently discovered that there are some ISPs in the world
that are blocking large chunks of European IP address space,
including (but not limited to) all the IP address space that belongs
to XS4ALL.nl, the ISP in the Netherlands that provides hosting for
all the python.org machines -- especially including the mail server.
The ironic thing is that XS4ALL is probably one of the most
pro-consumer/anti-spam ISPs in the world, and they are regularly
involved in lobbying the European government to get various
anti-consumer laws overturned or modified to be more appropriate.
They've even been strong enough to hold up against the Scientologists
in the US -- they provide hosting facilities for a well-known
anti-Scientology website, which had been hounded out of existence at
all previous facilities until it reached XS4ALL.
I'm going to be setting up my own co-location servers, and XS4ALL
is top of my list of sites that I will seriously consider for
security purposes, possibly including other sites at Sealand,
ServerVault (where a friend of mine used to work), and other highly
Anyway, if you're having delays in getting e-mail to your site
from this mailing list, one thing you want to check is to make sure
that you're not blacklisting or firewalling IP addresses belonging to
the network owned by XS4ALL.
