SpamAssassin cache hit inherits original spam score?

[Martin.Hepworth]

Correct, its a cache of recently seen email and it's spamassassin score..

See "SpamAssassin Cache Timings" for the actual timings used for ham, spam and high scoring spam....here's mine, which are the default.

# Do not change this unless you absolutely have to, these numbers have
# been carefully calculated.
# They affect the length of time that different types of message are
# stored in the SpamAssassin cache which can be configured earlier in
# this file (look for "Cache").
# The numbers are all set in seconds. They are:
# 1. Non-Spam cache lifetime                           = 30 minutes
# 2. Spam (low scoring) cache lifetime                 = 5 minutes
# 3. High-Scoring spam cache lifetime                  = 3 hours
# 4. Viruses cache lifetime                            = 2 days
# 5. How often to check the cache for expired messages = 10 minutes
SpamAssassin Cache Timings = 1800,300,10800,172800,600
