I just got the following in a spam message  which was 
not identified by spamcopuri even though the numeric
domain it is in sc.surbl.org

<a href=3D"">

The debug output shows that the uri is found
by the SA modules but that SpamCopURI 
queries for the wrong hostname.

It should be querying

> debug: uri tests: Done uriRE
> debug: checking url:
> debug: querying for 63.161..sc.surbl.org
> debug: Query failed for 63.161..sc.surbl.org

It looks like there are two problem is in SpamCopURI 
(v 0.15) in the routine _spamcop_uri 
    # strip any non alpha characters off of the end
    # this is to fix a bug where url parsing in core SA
    # leaves parens and other junk on the URL that URI
    # parses to the host

This causes the domain to become 69.63.161. 
(including a trailing dot)

(2) The domain is stripped back to a two level domain
even though it is/should be an ip address.
It becomes 63.161. (including a trailing dot)

This domain then does not match an ip address format
so it is not reversed and the lookup is done for 
63.161. added on to .sc.surbl.org, i.e.:


Eric, can you help?
