That's a crock. Blame the nice people at Teleglobe.net.

Semi-official function, being misused.

The *real* RBL is merely a list of sites that have spam problems.
The *INTENT* is that sites can *on their own* refuse to accept mail
from said sites. Sites that do not use the RBL are able to communicate
with the site.
However, I think it's a gross abuse to shut off ALL IP connectivity
to such a site, which is what the people at teleglobe.net are doing.

I suspect that the people at vix.com don't realize that a full IP
filter block is being used, and that they thought it was mail-blocking
only.
