This configuration is incomplete. Your logs should show an error about
that. Testing with sieve-test shows:
stephan at klara:~/src/devel$ sieve-test ~/frop.sieve ~/frop.eml
sieve-test(stephan): Error: sieve: spamtest: none of
sieve_spamtest_max_header or sieve_spamtest_max_value is configured
sieve-test(stephan): Error: sieve: spamtest: none of
sieve_spamtest_max_header or sieve_spamtest_max_value is configured
[...]
For example, your config should look like this (with max value 10; i.e.,
the value beyond which it is spam with 100% certainty):
sieve_spamtest_status_type = score
sieve_spamtest_status_header = X-Spam-Status: [^,]*,
score=(-?[[:digit:]]+\.[[:digit:]]).*
sieve_spamtest_max_value = 10
The sieve-test tool can be used to verify:
stephan at klara:~/src/devel$ sieve-test -t - -Tlevel=matching ~/frop.sieve
~/frop.eml
## Started executing script 'frop'
3: spamtest test [percent=false]
3: extracted score=84.600, max=10.000, ratio=100 %
3: starting `:is' match with `i;ascii-casemap' comparator:
3: matching value `10'
3: with key `0' => 0
3: finishing match with result: not matched
3: jump if result is false
3: jumping to line 4
