Leading zeros are required for values between (-1,1).
Thanks. After examine all the rules, found out that 70_sare_stocks.cf is
causing it.
It contains lines like:-
body SARE_MLB_Stock3 /Last[ _](?:Trade|Price)[ :]/i
score SARE_MLB_Stock3 .794
body SARE_LWSAFEH /Safe Harbor Statement:/i
score SARE_LWSAFEH .688
body SARE_LWOILCO /(?:oil|gas)\s+company/i
score SARE_LWOILCO .388
header SARE_LWSKY Subject =~ /skyr[o0]cket/i
score SARE_LWSKY .750
Removing it and spamassassin --lint not complaining anything else.
Thanks again
