OK, so those IPs DO have RDNS values that seem fine to me (point to a
real domain without an IP address in the PTR record).
What's more, the PTR records refer to valid A records that point back to
the same IP...
So it's pretty clear from this that your DNS resolution is failing.
1) Have you checked your own settings in /etc/resolv.conf? If that's
pointing you somewhere else, then having PDNS-Resolver on your system is
moot.
2) Have you checked these lookups on your own server?
*host 86.96.226.151* -- /resolves to domail1.emirates.net.ae/
*host domail1.emirates.net.ae *-- /resolves to 86.96.226.151/
That's at least a start...

qmlog yes, but spamdyke messages are in the smtp log. spamdyke
front-ends qmail-smtpd. The spamd log contains spamassassin messages.
Anywise, the errors in my case ended up being caused by one errant
nameserver name in the domain's registration. The errant nameserver did
not have the most recent updates, so queries would sometimes succeed and
sometimes fail. It was intermittent, and the luck of the draw whether
things would work or not.
Note, I was only able to find the problem because I had the real name. I
would have never found the problem with a reference to
whateverdomain.com. When trying to do problem determination of this
sort, it's imperative to have real data.
Vivek, if you continue to have a problem with a domain and would like
assistance, please post a spamdyke rejection message or two, from the
smtp log.
Thanks.
