	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 
secure facilities.

	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.
