the current dat version is 6675.0000
the spam engine is one behind. it should be 9309
the spam rules are also out of date. they haven't been updated since november. latest update will show
if you are epo managed then i would check that the epo repository has both the current dat and the spam engine listed in the epo repository
the spam rules are updated directly from the internet from this url http://su3.mcafee.com/su
if you have a firewall or proxy in place then it is most likely blocking access to the is site. the other reason would be the the "mcafee anti-spam rule updater" service isn't running.
then your firewall/proxy is blocking the connection to the spam rules update site.
check out this kb for possible issue with proxy servers
for firewalls make sure that access to su3.mcafee.com is allowed both outbound/inbound.
for the update error, does this server get updates from an epo server?
