LFD mails from other server suddenly treated as spam?

I check several servers and normally my mail address is in the alias so I also get root mail. In this case the sendering server is a cPanel server and some LFD mails are refused now.
But I can't find out why as they are not on any blacklist.

Reporting MTA somehosting is the cpanel server.
Code:
Reporting-MTA: dns; srv12.somehosting.nl

Action: failed
Final-Recipient: rfc822;[email protected]
Status: 5.0.0
Remote-MTA: dns; mail.mycompany.nl
Diagnostic-Code: smtp; 550-Your message to <[email protected]> was classified as SPAM.  Please
 550-add more content, cut down on HTML links, use fewer naughty words etc.
 550-Also, ask your IT dept to make sure your mailserver has REVERSEDNS, SPF,
 550 DKIM, and is not on any black lists. Your score: 156

156???
Sending server has both SPF and DKIM and correct rDNS and is not on any blacklist.
Normal root mails (like ssh login warnings) from LFD have no issues. So probably something in the content triggers the spam but I don't know where to look for it or what it can be.

Since rather shortly, don't know exactly since when, but this was not happening before.

In the log I see this:
Code:
drop message based on users high-scoring-spam setting (153 >= 150)
and
F=<> rejected after DATA: High scoring spam message has been dropped

I might be able to whitelist, but I would just like these mails to come through without isseus and don't know why these are suddenly seen as spam. Might have seen that in the past but age and memory leaks... :)
