Why was email filtered?

An email I was expecting was sent to /dev/null as spam. Looking at the logs it shows that SpamAssassin marked it as NOT spam. I dropped the raw source into the email spam filter test box and it passed. Here's the logs from exit_mainlog: [QUOTE]2020-01-15 14:42:12 1irjrz-0006Gz-Ll H=mout.kundenserver.de [212.227.126.133]:48297 Warning: "SpamAssassin as ddddd detected message as NOT spam (2.6)" 2020-01-15 14:42:12 1irjrz-0006Gz-Ll H=mout.kundenserver.de [212.227.126.133]:48297 Warning: Message has been scanned: no virus or other harmful content was found 2020-01-15 14:42:12 1irjrz-0006Gz-Ll <= phil@p*.co.uk H=mout.kundenserver.de [212.227.126.133]:48297 P=esmtps X=TLSv1.2:ECDHE-RSA-AES128-GCM-SHA256:128 CV=no S=50103 id=006501d5cbb1$db925d30$92b71790$@p*.co.uk T="Vibe SPec" for darren@d*****.com 2020-01-15 14:42:12 cwd=/var/spool/exim 3 args: /usr/sbin/exim -Mc 1irjrz-0006Gz-Ll 2020-01-15 14:42:12 1irjrz-0006Gz-Ll => /dev/null **.com> R=central_filter T=**bypassed 2020-01-15 14:42:12 1irjrz-0006Gz-Ll Completed 2020-01-15 14:42:12 SMTP connection from mout.kundenserver.de [212.227.126.133]:48297 closed by QUIT
Are there logs anywhere else I can look at to see why this was blocked? exim_rejectlog does not have this rejection. Thanks
