Ahh, I see you have a problem with Rspamd instead. You should look into whitelists in Rspamd. Rspamd is very strict about broken headers, so you might want to see if you can send with proper headers from the sender side or add an exception in Rspamd.

Good luck

The filters mark the message as spam but it can not say if it is the rspamd of the senderscore filter.

This is why I tried to bypass these filters with the white list.

    There is another server "test.example.org  <http://test.example.org>" with 
the same real user.

    When I send a mail from "[email protected]  <mailto:[email protected]>" to"[email protected]  
<mailto:[email protected]>", the message lands into the junk folder of"[email protected]  
<mailto:[email protected]>", instead of landing into the inbox.

    Is it junked by the Senderscore filter?

    Good luck,
