Graphs of DNSWL performance according to SpamAssassin Rule QA results.
Last update: 20200530.
On 2011-05-05, for bug 6557, the maximimum age limit for emails was changed to match what is used for score regeneration, from:
my $OLDEST_HAM_WEEKS = 52 * 10; # 10 years my $OLDEST_SPAM_WEEKS = 6 * 4; # 6 monthsto:
my $OLDEST_HAM_WEEKS = 72 * 4; # 72 months = 6 years my $OLDEST_SPAM_WEEKS = 2 * 4; # 2 months
Percentage of emails per trust level hit, which are not spam:
Current values with some possible short term goals:
99.9529305015756% of email DNSWL ranks as "high" is non-spam. (Goal: 99.99%)
99.1852989533395% of email DNSWL ranks as "medium" is non-spam. (Goal: 98%)
93.6319567377129% of email DNSWL ranks as "low" is non-spam. (Goal: 85%)
93.4679027148451% of email DNSWL ranks as "none" is non-spam. (Goal: 50%)
Percentage of ham that hits DNSWL per minimum rank:
Currently:
2.3563% of non-spam comes from an IP with a rank of "hi". (goal: 12.5%)
7.8371% of non-spam comes from an IP with a rank of at least "med". (goal: 25%)
11.4684% of non-spam comes from an IP with a rank of at least "low". (goal: 50%)
40.259% of non-spam comes from an IP that's listed in DNSWL at all. (goal: 100%)
S/O, SA's usefulness score per trust level:
0 = 100% non-spam (best)
0.5 = useless (half spam, half non-spam)
1 = 100% spam (worst for non-spam indicating tests like DNSWL)
This is basically a percentage of spam, with the numbers of spams and non-spams normalized.
Rank, 1 is best, 0 is worst:
I think they sort all SA rules by S/O (above) and scale the rank numbers to the range of 1 to 0.
