There seems to be a blacklist problem with spam from Korea.
As most of you will have experienced, they send massive amounts of spam. Most of it gets caught by my SpamAssassin settings, but the odd one that isn't very rarely gets caught by the korea blacklist, though it does work sometimes.
Just now, it failed again. Example:
http://www.spamcop.net/sc?id=z1114240632z7...ae0d29af4532a6z
Pinging 105.114.164.221.korea.services.net at the precise moment of reporting the spam showed that it resolved, i.e. that 221.164.114.105 is on the blacklist as it should be, but Spamcop still let it through.
Anyone else seeing that?
