You can use a custom SpamAssassin rule for this [0].

# /etc/mail/spamassassin/custom.cf
header   LOCAL_BAD_MSGID  Message-ID =~ /your-pattern/
score    LOCAL_BAD_MSGID  5.0
describe LOCAL_BAD_MSGID  Suspicious Message-ID

Then restart pmg-smtp-filter.

Yes, you can do this in Proxmox Mail Gateway: create a What → Match Field → EV trend charts object, select Message-ID, match the required value/regex, then attach a Mark Spam or Quarantine action. PMG supports matching Message-ID headers directly.
