[Rspamd-Users] Mail sent though mailman

[Klaus Rörig]

Hello everybody,

how can I solve this problem: mails going throught mailman get marked as 
spam, although the original mail is clean.

Users sent mails to the mailling lists from PCs, smartphones and the 
local webmailer (Roundcube).

This is the score of the incoming mail:

*MIME_GOOD* (-0.1) [text/plain]
*ARC_SIGNED* (0) [i=1]
*TO_DN_ALL* (0)
*RCVD_VIA_SMTP_AUTH* (0)
*NEURAL_HAM* (0) [-0.997,0]
*RCVD_COUNT_TWO* (0) [2]
*MID_RHS_MATCH_FROM* (0)
*DKIM_SIGNED* (0)
*TO_DOM_EQ_FROM_DOM* (0)
*ARC_NA* (0)
*HAS_ORG_HEADER* (0)
*FROM_HAS_DN* (0)
*RCPT_COUNT_ONE* (0) [1]
*FROM_EQ_ENVFROM* (0)
*TO_MATCH_ENVRCPT_ALL* (0)
*RCVD_TLS_ALL* (0)
*ASN* (0) [asn:24940, ipnet:2a01:4f8::/29, country:DE]

Then it goes throught mailman and is then scored with:

*BAYES_SPAM* (5.1) [100.00%]
*ARC_REJECT* (2) [signature check failed: fail, {[1] = 
sig:leibniz-remscheid.de:reject}]
*MAILLIST* (-0.2) [mailman]
*MIME_BASE64_TEXT* (0.1)
*MIME_GOOD* (-0.1) [text/plain]
*RCVD_NO_TLS_LAST* (0.1)
*HAS_LIST_UNSUB* (-0.01)
*RCVD_COUNT_THREE* (0) [3]
*FROM_NEQ_ENVFROM* (0)

*ARC_SIGNED* (0) [i=2]
*TO_DN_ALL* (0)
*RCVD_VIA_SMTP_AUTH* (0)
*NEURAL_HAM* (0) [-0.979,0]
*FORGED_SENDER_MAILLIST* (0)
*MID_RHS_MATCH_FROM* (0)
*PREVIOUSLY_DELIVERED* (0) [fk-mu at leibniz-remscheid.de]

Thank you,
