Hello,
I'm hoping someone can help troubleshooting using DCC in SpamAssassin.
My setup isn't populating the "X-Spam-DCC: : " header.
I installed SpamAssassin 4.0.0
spamassassin -V
SpamAssassin version 4.0.0
running on Perl version 5.38.2
I run Postfix 3.8.5
postconf mail_version
mail_version = 3.8.5
I setup Postfix to use SpamAssassin through a pre-queue milter over a unix
socket
smtpd_milters=unix:/run/sa-milter/sa-milter.sock
I installed DCC
cdcc -V
2.3.168
It can connect to its servers
cdcc info

# Re-resolve names after 12:29:46 Check RTTs after 11:46:45

What else can I check or change to get the DCC results populating the header?
Thanks.
