Hello,

I recognized, that some Spam arrived for multiple users, I checked the Spam info and found this in the scoreboard:

MAILING_LIST_MULTI -1 Multiple indicators imply a widely-seen list manager

I think, that this should be a +1 to rise the spam score. Where I can change this setting?

regards
Martin

Mailinglists are known to deliver to multiple people, and thus seeing a list header decreases the score intentionally, not increase it.

But yes, spammers are picking that up, they very often use spamassassin themself to see how they can "improve" their mails so that they get through easier. If you'd like to adjust that default, it's part of spamassassin which you can override through /etc/mail/spamassassin/custom.cf (empty by default). You might find the spamassassin documentation quite helpful: https://wiki.apache.org/spamassassin/AdjustRuleScore

Hope that helps,
Rhonda

add to custom.cf (you can choose your score level value):

# change the score level of mailing lists
meta MAILING_LIST_MULTI __HAS_X_LOOP + __HAS_X_MAILING_LIST + __HAS_X_MAILMAN_VERSION + __HAS_X_BEEN_THERE +__DOS_HAS_LIST_UNSUB + __ML1 + __ML2 + __ML3 + __ML4 + __ML5 > 2
describe MAILING_LIST_MULTI Multiple indicators imply a widely-seen list manager
score MAILING_LIST_MULTI 1

Use custom scores in GUI to change the default score.
Added custom score MAILING_LIST_MULTI - did not work, after added to custom.cf - it worked.

Maybe we should use a different value in the custom score instead of MAILING_LIST_MULTI?
