I am just guessing here, but I think the examples show two different situations:
On the first example, it looks like SpamAssassin didn't like the
contents (headers included) of the message and scored it tooo high
(16.2). I am not sure what is the score above which the mail is
rejected, but I think it's 15. I use it a bit lower, 12 I think.
On the second example, the problem is that the IP from which the
message came has no reverse DNS and spamdyke doesn't like such. I
guess that there must be a way to configure spamdyke not to do that
check. I thought that checking for reverse DNS had been almost
abandoned, as many think that the overhead involved doesn't compensate
the gains, namely because many of the big spammers have reverse DNS.
