By all means, shut off relaying immediately if you haven't already.

Do you have more specific netblocks?  A /16 is almost certainly not entirely
owned by one entity.  You can check some of the specific IPs with the major
spam blocklists like the SBL (http://www.spamhaus.org/sbl/) or SPEWS
(http://www.spews.org) to see if they've tracked those sources back to one
particular spammer or spamgang.
