Dear Fred,

Those IP addresses were appropriately listed by IP based blacklist(s).
I suggest you to try the DNSBL provider cbl.abuseat.org.
Here is my statistics from the time range of 1st of November till
4th of November of spam e-email delivery attempts filtered by the
IP list you provided:

     83	124.6.159.130
      2	115.230.76.104
      1	1.199.184.250
      1	122.241.3.11
      1	222.189.144.75

The number of spams from these IP addresses which got through the filtering: 0.

Take care.

Best,
Attila
