We had to remove Oxmail’s checking of URIs against the URIBL blacklist a couple of weeks ago after a change of licensing meant that we could no longer use it for free.
JANET(UK) has now purchased a private datafeed and offers lookups via multi.uribl.dnsbl.ja.net.
Oxmail’s SpamAssassin is once again scoring URIs which show up in this blacklist. As an added bonus we gain access to the Gold blacklist by virtue of using the paid-for datafeed.
