The default was 5, and I lowered it to 4 because too much spam went
through. :-) (Mainly because I have inherited a couple of domains that
had no spam control at all for years. They are now set up with spf and
some restrictions on the receiving end for the sender domain . Amazing
how little spam makes it through just with those basic checks!)
Not overly concerned about malware. That we can handle here with
common sense and antivirus software. (Probably should not say that!
Touch wood)
It is interesting that spamd classifies this as non-whitelisted, whilst
the mail server must be classifying this as non-blacklisted since it
is reaching me. The mail server is doing all sorts of checks before
accepting the incoming mail, and clearly the DPD mail passes all that.
But then again, maybe that is because it is forwarded from Hotmail...
Anyway, thanks for the suggestions! I'll go ahead and create my own white
list configuration.
Cheers,

Whilst it's cheating a bit you could always try
increasing your spam
threshold to 5 as you may find it works around the problem without any
unwanted side-effects as 'real' spam all too often scores way higher.
This may prove more reliable than letting messages
through based on the
source address as courier firms are commonly spoofed to send malware
disguised as delivery notices.
